What to Look For

Warranty Transferability

Some warranties transfer to new owners if you sell your home. This can increase property value. Check if warranty is transferable before purchasing.

Manufacturer Reputation

Choose panels from established manufacturers with good track records. A 25-year warranty is only valuable if the company is still in business to honor it.

Frequently Asked Questions

Q: Does homeowner's insurance cover solar panels?

A: Usually yes, for permanently installed systems. They're typically covered under your dwelling coverage. However, you may need to increase your coverage limit if the system value is high. Portable systems may need separate coverage. Always confirm with your insurance provider.

Q: What if my panels stop working after warranty expires?

A: After warranty expires, you're responsible for repairs or replacement. However, quality panels typically last 25-30 years. The performance warranty guarantees minimum output, so even if efficiency degrades, panels should still produce electricity. Replacement costs are usually reasonable after 20+ years of savings.
