With electricity costs rising and incentives available, more homeowners are exploring residential solar systems. This guide explains everything you need to know, from choosing panels to installation options, costs, and insurance.

How Solar Panels Work for Your House

Solar panels home systems capture sunlight and convert it into electricity that powers your house. A typical residential solar setup includes:

• Solar panels – the main component that generates electricity
• Inverter – converts solar power into electricity for your home
• Battery storage (optional) – stores excess energy for nighttime or outages
• Mounting hardware – secures the panels to your roof

A properly sized home solar system can cover most of your electricity usage. The number of panels house requires depends on your energy consumption, roof size, and sunlight exposure.

For more details on system sizing, see our Understanding Residential Solar System Sizes guide.

How to Size Solar Panels for Your House

One of the most common questions is: “How do I size solar panels for my house?”

• Review electricity usage – Check past bills to determine your average monthly kWh.
• Calculate system size – Divide your annual usage by the expected energy output of your panels.
• Pick the panels – For example, modern panels produce 370–420 watts each. Divide your system size by the panel wattage to estimate the number of panels home needs.
• Check roof space – Orientation, shading, and roof structure affect panel placement and efficiency.

You can also explore solar kits if you’re considering a DIY approach. Kits include panels, inverters, and mounting hardware, making it easier to plan your system.
