What is a Residential Solar System and How Does it Work?

A residential solar system consists of solar panels made up of photovoltaic cells, which convert sunlight into usable electrical energy. Other essential parts of the solar system include an inverter and a net meter. Batteries are used to save extra electricity produced during the day.

1. Solar Panels/Solar Plates
2. Inverter
3. Battery Storage (Optional)
4. Net Meter

1. Solar Panels/Solar Plates

Solar panels are photovoltaic cells that convert sunlight into electrical energy. They are made up of semiconducting materials that are light-sensitive. Solar panels are the most important part of the solar system and they longer life duration than any other part.

2. Inverter

The inverter is among the important components of the solar system. It converts direct current from solar panels into alternating current. Alternating current is the form of electricity that is consumed by electrical appliances in homes. The latest inverters have a feature that monitors the performance and production of the solar system.

3. Battery Storage (Optional)

Batteries are not necessary if you want to use a solar system for day use only. Having battery storage is a plus point that allows you to save the surplus amount of electricity that can be used at night, further reducing dependence on grid power and electricity bills. Batteries are a good option if easily affordable.

4. Net Meter

A net meter monitors the amount of energy your solar system sends to the grid and you consume from the grid. If you send more energy to the grid than you use from it, you will get credits or payment from the utility company. This makes solar cost-effective and eco-friendly.

Is Your Home a Good Fit for Solar in 2025?

It is important to evaluate the condition of your home structurally and geographically to check whether it is in optimal condition or not.

Here are some factors that you must consider before investing in a residential solar system.

• Roof Orientation and Space: The roofs having face in south usually receive more sunlight and are better for solar installation. A spacious and unobstructed roof is required for maximum solar panel installation.
• Roof Condition: The roof of your home must be in good condition. It supports the long-term performance of the system and avoids premature removal of the system.
• Tree Coverage/Shading: The place should be free from any excessive shading due to trees, buildings, or chimneys. A professional solar assessment helps you determine whether your space is ready or not.
• Local Climate: The climate affects most in solar energy production. Homes in sunny areas produce consistent solar energy, while areas where the weather is mostly cloudy require high-efficiency panels.
