How to Choose a Solar Energy System For Home

Solar energy systems for home provide a clean, renewable source of electricity that can save homeowners on utility bills. These systems can also help reduce carbon emissions and contribute to a cleaner environment.

Solar panels produce DC (direct current) power, but the appliances in our homes use AC (alternating current) power. To convert from DC to AC, a home solar system requires an inverter.

Solar panels

Solar panels are the heart of a home solar energy system, and they’re available in a wide range of wattage to fit most projects. The solar panel size is a crucial factor in your overall cost, so you should have an idea of the dimensions of your roof and your project site before choosing a panel type. The wattage of the solar panels depends on how much sunlight your location gets during peak sunlight hours and how electricity is priced in your area.

After the solar panels are installed, a power inverter converts direct current (DC) electricity from the panel into alternating current (AC) that can be used to power appliances. The inverter is usually placed after the batteries and power controller, but you can choose to have it before the connection to your home.

Most home solar systems are “grid-tied,” which means they’re connected to both the local utility grid and your house’s electrical system. The energy your solar panels produce during the day is first used in your home, and any excess can be pushed onto the grid through net metering.

Many home solar installation companies offer a variety of financing options, such as paying in one lump sum, getting a loan or entering into a lease or Power Purchase Agreement. Each option affects your upfront costs and qualifies you for different tax incentives. Some companies, like SunPower, also offer 25-year warranties on their products and provide performance guarantees that promise a certain amount of energy production over the life of your solar system.


An inverter converts DC solar energy into AC electricity for use in your home. It’s important to choose a quality inverter that is compatible with your devices and appliances, as well as your home’s power consumption and solar panel output. A good inverter should also be capable of handling peak loads, such as those from appliances that have high starting currents. A qualified installer can help you decide which inverter is right for your home.

There are three different types of solar inverters: string, microinverters, and central inverters. String inverters are the most common and SOLAR INVERTER simplest to install, and they’re cheaper than other options. They’re best for homes that don’t have a lot of shade or other factors that may affect a solar system’s performance. However, they’re not as efficient as other options.

A microinverter system uses individual solar inverters installed at each of the solar panels outdoor pathway solar lights in a row. These inverters are more expensive than string inverters but can maximize energy yield by managing each panel’s output. They’re also more flexible and can accommodate complex solar arrays with shading, mismatched modules, or different panel orientations. A microinverter system can even include a device called a power optimizer, which relays information to each individual solar panel and optimizes their performance.


A solar battery stores electricity that the panels produce during the middle of the day when the home uses less energy. With a standard grid-tied solar system, this excess power goes back to the utility grid. When paired with a battery, however, the system can send that electricity to the house at night and during power outages.

A battery can also help a homeowner save money on their electric bill by using load shifting. It prioritizes the use of stored solar energy over grid electricity during peak usage times, resulting in significant savings.

Some solar customers are also interested in a backup to keep appliances running during a power outage. A battery system combines a solar array with an inverter that can switch to grid or battery power as needed. This type of hybrid solar system is a good choice for many homeowners, since it gives them the best of both worlds.

When installing a solar battery system, it’s important to size the capacity of the batteries correctly. A battery’s storage capacity is measured in kilowatt-hours (kWh). It’s best to size the battery based on your household loads. Larger batteries can support more of a home’s loads during an outage, but if they are too big, the batteries can get depleted too quickly and may not last long enough to be useful. To minimize this risk, installers usually add a critical load panel to the solar system that only draws from the battery when necessary.


Before installing a solar energy system, it is important to understand the basic principles of wiring. This will help you determine whether you need to use parallel, series, or combination wiring methods. Each method works differently and will affect your power output. If you are unsure, contact a professional for help.

Solar energy systems use a battery to store electrical energy generated during the day for use at night. The battery also protects the solar panels from damaging by absorbing excess current and eliminating power losses. In addition, it helps to maintain a consistent voltage output throughout the day.

There are two common wiring techniques for PV solar systems: Daisy Chain and Leapfrog. Daisy Chain is a simple way to wire solar panels in series, while leapfrog saves money on wire and reduces power losses by jumping one panel over another. Both are effective for most situations, but the best way to determine which method is right for your home is to talk with a local installer and ask them about their recommended wiring practices.

Wiring for PV solar systems must follow NEC (National Electric Code) regulations. These include proper conductor size and overcurrent devices. In addition, all connections should be made with a good quality copper or aluminum wire. A stranded wire consists of multiple conductors that are twisted together and covered with a jacket, while standard wire is solid and has a higher amperage capacity.
