Use parallel wiring to increase current (power)
Use parallel wiring to increase current (power)
This diagram shows a simple parallel circuit to increase current or power. Assume that we are using 12 volt batteries. The power of all 3 batteries add to give us the effect of a battery 3 times as powerful but the voltage stays the same at 12 volts. Parallel wiring increases current but the voltage does not change. This is the wiring used when jump starting a car for example.
Use series wiring to increase voltage
This diagram shows a simple series circuit to increase the battery voltage level. Assume that we are using really big 4 volt industrial batteries.
The voltage of all 3 batteries add to give us the effect of a battery 3 times the voltage or in this case a very large 12 volt battery. In this circuit the current is the same as the current in just 1 of the batteries. But since the 4 volt industrial batteries are very large, we have in effect created a huge 12 volt battery.
Use series & parallel wiring in combination
This diagram shows a combination series and parallel circuit to increase both the battery current and voltage level at the same time. Assume this time we are using 12 volt batteries.
The left to right series connection add the two 12 volt batteries to make 24 volts. And, since we did this 3 times and then connected each group of 2 (now 24 volts) in parallel we end up with one very large 24 volt battery. It has twice the voltage of a single 12 volt battery and 3 times the current or power because all 3 groups are wired in parallel.
Solar Energy Systems wiring diagram examples
Click the 3 buttons below for examples of typical wiring layouts and various components of solar energy systems in 3 common sizes: 2 KiloWatts, 4 KiloWatts, and 8 KiloWatts. These system sizes are based on 100 watt solar panels and 5 hours of average daily sunshine. This is explained in greater detail in our tutorial on Solar Radiation. Of course, under actual operating conditions a solar power system does not produce full output every day.
These diagram examples could represent 12, 24, or 48 volts systems. The basic wiring configuration would be the same for any voltage system. These diagrams are meant to give a general idea of typical system wiring. Certain grounding and fusing circuits have been omitted from the wiring diagrams for clarity.

Storage Batteries : the fuel tank of your solar power system
Without batteries to store energy you would only have power when the sun was shining or the generator was running. This tutorial describes the 4 basic types of batteries & provides some good tips on the care & feeding of your batteries to maximize their performance and life.
1) RV / Marine / Golf Cart : RV or Marine type deep cycle batteries are basically for boats & campers and are suitable for only very small systems. They can be used but do not really have the capacity for continous service with many charge/discharge cycles for many years. Regular or Car type batteries should not be used at all because they cannot be discharged very much without internal damage. A very popular battery for small systems is the Golf Cart battery. They are somewhat more expensive than deep cycle recreational batteries but are probably the least expensive choice for a small system on a budget.
Industrial strength : Flooded, Gel, and AGM sealed batteries
The next 3 types are the heavier industrial type batteries. They are all also considered Deep Cycle and are usually Lead Acid types with much thicker internal plates that can withstand many deep discharge cycles. These next 3 are all designed for alternative energy systems.
2) These are Lead acid batteries that have caps to add water. Many manufacturers make these types for Solar Energy use. Trojan, Surrette, and Deka are probably the most well known. They are reasonably priced and work well for many years. All flooded batteries release gas when charged and should not be used indoors. If installed in an enclosure, a venting system should be used to vent out the gases which can be explosive.
3) Not to be confused with maintenance free batteries, sealed gel batteries have no vents and will not release gas during the charging process like flooded batteries do. Venting is therefore not required and they can be used indoors. This is a big advantage because it allows the batteries to maintain a more constant temperature and perform better.
4) Absorbed Glass Mat batteries are in my opinion the best available for Solar Power use. A woven glass mat is used between the plates to hold the electrolyte. They are leak/spill proof, do not out gas when charging, and have superior performance. They have all the advantages of the sealed gel types and are higher quality, maintain voltage better, self discharge slower, and last longer. The Sun Xtender series by Concorde Battery is an excellent example of AGM batteries. They are more expensive, but you usually get what you pay for. You will find this type of battery used in airplanes, hospitals, and remote telephone/cell tower installations.
Care and Feeding
As a technician, I used to say that if you are not comfortable, then neither is your equipment. I was mostly referring to temperature and humidity. In fact battery capacity ratings are usually specified at 77 degrees F. As batteries get colder their voltage drops and performance suffers. This is one major reason I prefer AGM batteries because they can be stored indoors where the temperatures vary less.
Another important thing to consider is how deeply you discharge your batteries. This is known as the DOD (depth of discharge). In other words, how low you let the voltage drop before the next charge cycle. Most battery ratings talk about 50% or so, but they will last longer if you keep them as charged as possible. I like the 70% range. Lead acid batteries like to be fully charged. They will last much longer if you do not discharge them too deeply. This is known as shallow cycling and greatly extends their life. However, they can withstand discharges down to 20% or so, but I wouldn't do it too often.
How to determine how charged your batteries are
Determining the percentage of battery charge from meter readings is discussed in more detail under Meters and Monitors. A common voltmeter and this voltage chart will give you a good idea of the SOC (state of charge) of your batteries.
Monitoring battery voltage and system performance
It is important to know the state of your system. Specifically, you need to keep close watch on the SOC (state of charge) of your batteries. By not allowing your batteries to discharge below a certain point you can greatly improve their performance and extend their life. Monitoring the Voltage and Current readings in your system will tell you how full your batteries are and how fast they are charging or discharging. All this can be monitored with one or more meters. I like to have one meter continously display the Solar Panels charging current and a multi-function display for Voltage, AmpHours, another functions.
A short electronics lesson
Voltage : is the equivalent of the water pressure in a water pipe.
Current : is the equivalent of the rate of water flowing in a water pipe.
Current : is the equivalent of the rate of water flowing in a water pipe.
Power : is the amount of water flowing thru the pipe based on the water pressure AND the rate of flow.
Check out the Watts & Power tutorial for more details on voltage, current, and power.
Definitions
Voltage : is the electromotive force (pressure) applied to an electrical circuit measured in volts (E).
Current : is the flow of electrons in an electrical circuit measured in amperes (I).
Resistance : is the opposition to the flow of electrons in an electrical circuit measured in ohms (R).
Power : is the product of the voltage times the current in an electrical circuit measured in watts (P).
Ohm's Law
In its simplest form, Ohm's law states that the current in an electrical circuit is directly proportional to the applied voltage and the resistance of the circuit. The 3 most common mathematical expressions are:
E=I*R I=E/R R=E/I
Also, the power can be expressed as P=E*I and with a little algebra we can combined these expressions and derive P=E² / R
So what does all this mean? Well, for one thing it becomes clear that an appliance (load) that draws 1 amp (ampere) of current at 120 volts will draw 10 times as much current at 12 volts (1/10 the voltage) or 10 amps. Since P=E*I then 120 volts times 1 amp = 120 watts. Also, 12 volts times 10 amps = 120 watts. So you can see that the power remains the same. As the Voltage goes down, the Amperage increases to maintain the power which will be determined by the 3rd factor, resistance.
Ok, now let's say you have a nice 1200 watt hairdryer. Well, that would work out to 10 amps at 120 volts. But, when your power inverter uses the 12 volts supplied from your batteries, the amperage goes up to 100 amps to produce the same 1200 watts! (P=E*I). This means that even the very large cables connecting your batteries to the inverter will get warm. This is why it becomes impractical or impossible to run say, a 4000 watt electric clothes dryer. Even if you had large enough wires to handle the required 333 or so amps, your batteries would not last long.
It is true that the cables will not get as warm if the current can be reduced by increasing the voltage by using a 24 volt battery system or even a 48 volt battery system. This still will not change the amount of power that your batteries must supply.

The 12 basic formulas for Ohm's Law can be expressed as follows :
- Voltage = the Square Root of Power * Resistance
- Voltage = Power / Current
- Voltage = Current * Resistance
- Resistance = Voltage / Current
- Resistance = Power / Current squared
- Resistance = Voltage squared / Power
- Current = Voltage / Resistance
- Current = the Square Root of Power / Resistance
- Current = Power / Voltage
- Power = Voltage * Current
- Power = the Current squared * Resistance
- Power = the Voltage squared / Resistance
Summary
The upshot of all this is twofold:
1) You will need to replace electric appliances that need large amounts of power with gas (natural or LP) or other alternatives. This would usually be anything that uses 1500 watts or more. All appliances that are UL rated will have their power consumption in watts listed on a placard or label near the AC cord.
2) When you find the wattage listing you can divide by 120 to get the number of amps the appliance will require. Multiply this number by 10 for a 12 volt system to determine the number of amps that will be drawn from the batteries. For a 24 volt system, multiply by 5. For a 48 volt system multiply by 2.5.

Deep Cycle Battery Banks 101
The battery bank is one of the most complicated and costly components of any off-grid Solar power system. Your battery storage needs to be large enough to supply power year-round. Nothing is more frustrating than suffering a power outage because your battery bank doesn't store enough charge. On the other hand, too much battery capacity means your system won't be able to fully recharge. If your battery bank is too large, your batteries can't get the full charge, which can ruin the batteries. Dialing in on the right battery bank is an important step to designing your off-grid system. You want to make sure you hit the sweet spot.
What's in a Battery Bank?
A battery bank can be composed of a single battery, or multiple interconnected batteries that are wired to work as one large battery at a certain voltage and amp-hour capacity.

Acoplamiento AC es realmente sólo la adición de batería de reserva para una instalación fotovoltaica de conexión a red existente.
La mayoría de los sistemas solares conectadas de la rejilla no incluyen un método para almacenar la energía que el sistema está produciendo y se apagará durante un corte de energía de la red. Cuando la red se apaga, lo mismo ocurre con sus sistemas de energía solar. Mediante la adición de baterías, puede almacenar la energía que el panel solar está produciendo y utilizarlo durante un apagón eléctrico. Lo que hace que otros sistemas de energía solar fuera de la red de la selva virgen y enfocado empresas especialmente cualificado para diseñar y vender sistemas acoplados de AC es que realmente entendemos los sistemas de almacenamiento de la batería. Muchos instaladores solares de conexión a red no han trabajado con baterías antes, y muchos optar por seguir no funcionar con baterías. Eso no quiere decir que tiene que ser desalentador para el dueño de casa. Esto ha hecho esto fácil mediante el diseño de varios kits con inversores Magnum PAE y baterías AGM selladas libres de mantenimiento. Cada sistema se basa en la cantidad de tiempo y tamaño de las cargas que desee hacer copias de seguridad durante un corte de luz. La mayor parte de los componentes ya vienen, así que con la adición de unas cargas críticas sub-panel, se puede comenzar a almacenar energía para su uso cuando realmente lo necesita, cuando las luces se apagan todas partes. Los sistemas siguen trabajando durante el día, la carga de las baterías y proporcionar energía a las cargas de respaldo durante todo el período negro de salida. Así día o de la noche, tendrá el poder para su uso en su hogar. cargar las baterías y proporcionar energía a las cargas de respaldo durante todo el período negro de salida. Así día o de la noche, tendrá el poder para su uso en su hogar. cargar las baterías y proporcionar energía a las cargas de respaldo durante todo el período negro de salida. Así día o de la noche, tendrá el poder para su uso en su hogar.
Cómo acoplamiento Obras AC
AC acoplamiento es el proceso de atar en una base, el inversor / cargador fuera de la red de la batería adicional. El inversor / cargador trabaja junto a la cadena de conexión a red existente o micro-inversores, manteniendo el sistema en funcionamiento durante un corte de energía. Un panel de críticos cargas sub es necesaria para esta aplicación. El "cargas críticas" sub panel es un panel de interruptores adicional que es independiente del panel del interruptor principal de un edificio, designado sólo para aparatos de copia de seguridad durante los cortes de energía. Cuando diseñamos y tamaño de la porción de respaldo de un sistema de acoplamiento de AC, lo miramos de manera similar a un sistema autónomo fuera de la red o sistema de micro-rejilla. El sistema se "en isla" durante un corte de luz, que funciona de manera muy similar a un sistema fuera de la red tradicional, sin entrada de red. Hay un par de diferencias únicas con un sistema acoplado de AC en términos de dimensionamiento para que coincida con la matriz de conexión a red existente y la falta de controladores de carga. Nos entrar en más detalles sobre esto más adelante en el artículo. Cuando la red está activa, la energía está fluyendo a través de la Magnum inversor / cargador a las baterías para mantener su carga. Su rejilla inversor conectado funcionará normalmente, la venta de energía a la red y fuera de la configuración de las cargas, tanto en el panel principal y sub panel. Cuando se produce un negro-out, el Magnum inversor / cargador sin problemas comienza a invertir potencia del banco de baterías para alimentar sólo las cargas en las cargas críticas sub panel. El inversor de red conectado no puede detectar la desconexión de la fuente de alimentación principal debido a la Magnum estar en línea y continúa para alimentar energía al sistema. La adición de un reequipamiento de conexión a red a su sistema de conexión a red existente no requiere ningún cambio en el cableado existente solar. El cableado más complicado será el movimiento de las cargas que desea el poder durante un corte de utilidad para los interruptores de la nueva "cargas críticas" back-up panel secundario. La salida de AC del sistema de rejilla-tie existente también se moverá a las cargas críticas sub-panel. baterías de respaldo deben ser protegidos de la sobrecarga durante los períodos de interrupción de la red. inversores Magnum Energy PAE pueden programarse para cambiar su frecuencia de salida ligeramente ajustando el tipo de batería de "Configuración personalizada". Cuando en este modo, el inversor Magnum cambiará su frecuencia de 60,6 Hz cuando el voltaje de la batería llega a 4 voltios más alta que la absorción de tensión en un sistema de 48 voltios. Esto hará que el inversor de la rejilla-tie para apagar durante 5 minutos, detener la batería de carga y permitiendo que las cargas se alimente de las baterías. Después de 5 minutos el inversor de red-tie se enciende de nuevo y comienza a cargar las baterías. Este proceso se repite mientras el sistema de conexión a red está haciendo más energía que la casa cargas están utilizando. Solar proporciona un relé que se comunica con el enrutador Magnum para desconectar el inversor de la rejilla-atado y la matriz solar cuando la red está inactiva, el sol brilla y se produce más potencia que se consume a través de las cargas críticas sub panel. Al igual que en el método anterior, cuando el voltaje de la batería sube a una tensión de pre-set el relé disparará, desconectar el inversor de red-lazo.
¿Cómo puedo configurar una Cargas críticas Subpanel?
En primer lugar, determinar qué cosas que no se puede vivir sin él durante un apagón. La mayor parte del tiempo que habría un refrigerador, algunos circuitos de luz y de energía, y tal vez una bomba para pozos, etc. La cantidad mínima de cargas que transfiera resultado en una reducción en la cantidad de baterías que se requieren para alimentar las cargas. Ver nuestra página sobre la evaluación de la carga y el cálculo, incluyendo una hoja de trabajo de evaluación de carga que se puede utilizar para determinar el tamaño de las cargas que desee hacer copia de seguridad. Una vez que haya determinado las cargas que desee hacer copias de seguridad y la cantidad de tiempo que desea estar preparado para realizar copias de seguridad, podemos ayudar a determinar el tamaño de la batería requerida. Este tipo de trabajo debe ser realizado por un contratista electricista o eléctrico calificado y permisos puede ser necesario en algunas jurisdicciones.
Dimensionar el banco de baterías
En primer lugar pensar en la cantidad de tiempo que su potencia es típicamente, un par de horas a varios días. Esto va a determinar; junto con el tamaño crítico de las cargas, la capacidad total necesaria dentro del banco de baterías. En un esfuerzo por simplificar el proceso, todos nuestros sistemas de bancos de baterías se muestran en vatios-hora (Wh). La cantidad total de vatios sus cargas críticas consumir veces la longitud de tiempo que desea copia de seguridad de esas cargas (duración de la interrupción) determinará el tamaño del banco de baterías para el sistema. Planear para el peor de los casos, en términos de las condiciones meteorológicas. Aunque el sol puede estar brillando durante las horas de luz de un corte de luz, la mayoría de las veces experimentamos interrupciones durante las tormentas severas tiempo que tienen condiciones de poca luz. Esto significa que usted no puede experimentar la salida completa del poder de su panel solar.
El dimensionamiento del acoplamiento de AC, Retro-Fit general Tamaño del sistema
¿Qué sistema acoplado de AC es para usted? El inversor Magnum tiene que tener una potencia 10% mayor que la potencia de producción de la matriz solar después de reducción de potencia para las ineficiencias del sistema. Si tiene varios inversores string conectadas a la red cableados en paralelo dentro de su sistema, que sólo es posible utilizar uno de los inversores y una porción de la matriz para fines de copia de seguridad. Para sistemas con micro-inversores, si tiene varias cadenas de micro-inversores cableadas en su panel principal, que sólo es posible utilizar la misma metodología y utilizar sólo una parte de la matriz y los inversores con fines de copia de seguridad.

Infinite Tile Warranty
Made with tempered glass, Solar Roof tiles are more than three times stronger than standard roofing tiles. That's why we offer the best warranty in the industry - the lifetime of your house, or infinity, whichever comes first. Watch our hail test video to see how we take durability to a whole new level.
Power your Home with Beautiful Solar
Solar Roof complements your home’s architecture while turning sunlight into electricity. With an integrated Powerwall battery, energy collected during the day is stored and made available any time, effectively turning your home into a personal utility. Glass solar tiles are so durable they are warrantied for the lifetime of your house, or infinity, whichever comes first
Invisible Solar Cells
Customize the amount of electricity your Solar Roof produces to fit your energy needs. This feature is made possible by using two types of glass tile, solar tile and non-solar tile. Both appear the same from street level.

Meet Powerwall, your home battery
How we generate your recommendation
Tesla recommends 2 Powerwalls
Based on your estimated energy usage: 31 kWh/day
How does Powerwall work during an outage?
Meet Powerwall, your home battery
Value of energy
The value of energy your Solar Roof is expected to produce over 30 years is based on the average price of electricity in your area, adjusted for inflation by 2% annually. Your ability to realize the full value depends on your home’s electricity usage, amount of energy storage available, and utility regulations on solar in your area. Electricity price estimates are sourced from the Energy Information Administration and solar production estimates are based on irradiance data from NASA.
Cost of roof
The estimated cost of your Solar Roof includes materials, installation, and the removal of your old roof. Taxes, permit fees and additional construction costs such as significant structural upgrades, gutter replacement, or skylight replacements are not included. The Solar Roof cost is based on estimated roof square footage for your home, provided by Google Project Sunroof where available, and the portion of your roof covered with solar tiles.
Cost of Powerwall battery
The estimated cost of your Powerwall includes the battery, supporting hardware and installation cost. We recommend that every Solar Roof be installed with a Powerwall battery to enable you to use more of the solar power your roof produces and keep your home running during a grid outage. In states that do not have Net Energy Metering policies, we estimate and recommend a number of Powerwalls that will enable you to realize the full benefit of the energy your Solar Roof produces.
Tax credit
The 30% Solar Investment Tax Credit applies to the cost of the solar tiles and associated solar energy equipment as well as the cost of the Powerwall batteries. To receive the full tax credit, you must have federal income tax liability that’s at least equal to the value of the tax credit. This credit may be carried over to future tax years. Additional state, local or utility solar incentives may apply but are not included in this calculation.
Monthly loan payment
Customers can choose to finance their Solar Roof through their home mortgage. The loan amount is equal to the total Solar Roof cost, less the estimated 30% federal tax credit. The monthly loan payment is amortized over the selected loan term at the selected interest rate. Tesla is not a mortgage lender. Values depicted above are for illustrative purposes only.
Mortgage interest deduction
A benefit of financing a Solar Roof through a home mortgage is the tax deduction customers may receive on their mortgage interest. This value decreases over time as the mix of principal and interest paid per month shifts. The value of the mortgage interest deduction will vary depending on customers’ tax rates and individual financial information. This is not tax advice. Please consult your tax advisor.
Traditional roof cost
A typical asphalt shingle roof cost starts at $5 per square foot. The monthly loan payment for a traditional roof is estimated using the same loan term and interest rate as is selected for the Solar Roof for a given roof size.
Recommended solar tile coverage for your home
We recommend the portion of solar tiles for your roof that we estimate will produce enough electricity to cover your home energy usage. To customize your usage, enter your average monthly electric bill. If you choose to increase the portion of your roof covered with solar tiles, your home may generate more electricity than it needs. In this case, you may not realize the full value of energy your Solar Roof produces. Your entire roof is not eligible to be covered with solar tiles due to building regulations and obstructions. Recommended solar tile coverage is based on estimated eligible roof area for solar.
Warranty and specs
All warranties and ratings apply to the United States only. Similar warranties and ratings will be developed for other markets. Our tile warranty covers the glass in the tiles. The power warranty covers the output capability of the solar tiles. Weatherization means that there will be no water leaks or other weather intrusions during the warranty period that result from our installation.
Installation timing
Initial trial installations are complete and customer installations are underway with plans to ramp up in 2019. When Solar Roof is rolled out in a particular market, Solar Roof customers will be installed based on when their order was placed. Installations performed by Tesla, Inc.’s wholly owned subsidiary SolarCity Corporation. CA CSLB 888104, MA HIC 168572/EL-1136MR. View our full list of contractor licenses online.
What is a self-powered home?
A self-powered home combines solar energy and Powerwall to independently power your home day and night. During the day, solar panels may produce more energy than your home uses. Powerwall stores that excess solar energy and makes it available on demand, even after the sun has set. Through the Tesla app, you will have full visibility into your self-powered home.
