Frequently Asked Questions(FAQ)

How many solar panels are needed to run a house off-grid?

The number of solar panels needed to power a house off the grid depends on the home's energy consumption. For a typical American home that consumes 11,000 kilowatt-hours annually (based on the average monthly electricity usage of 877 kWh per month), around 13 solar panels of the expected output would be sufficient. However, you will need fewer panels if you have a smaller home or RV. 

What’s the average lifespan of an off-grid solar system?

Solar panels typically last 25 to 30 years. Reputable manufacturers usually provide production warranties that last for 25 years or more. On average, homeowners can expect to break even on their solar panel investment six to 10 years after installation due to energy savings.

Can I DIY install an off-grid solar system?

It is possible to DIY install an off-grid solar system, but it is not recommended unless you have experience in electrical and construction work. Installing solar panels and other components requires specific knowledge and expertise to ensure they are installed safely and correctly. Mistakes can lead to system inefficiencies, safety hazards, and damage to equipment, which can result in expensive repairs or replacements. 

How do I choose the right off-grid solar system for my needs?

To choose the right off-grid solar system, consider your energy needs, location, and budget. Determine how much power you need and how many solar panels and batteries will meet your requirements. Choose high-quality and efficient equipment from reputable manufacturers. Decide whether to hire a professional or DIY the installation. Consider ongoing maintenance costs and warranties. Do your research and compare different options before making a decision.
