The cost will vary depending on your requirements. Our Solar PV Engineers will design a system that is suited to your electricity usage, available roof space, and budget. As a rule of thumb, payback duration for solar power systems is typically about 6 years for home owners, and about 4 years for business owners. So to get a rough estimate on how much a solar power system will cost you, decide on how much you want to save a month, and multiply that with 72 months or 48 months accordingly.
