On-Grid Systems are solar pv systems that only generate power when the utility power grid is available.They must connect to the grid to function.They can send excess power generated back to the grid when you are overproducing so you credit it for later use.
Conclusion: They are simple enough that you can install it yourself in a weekend with a friend. They are cost effective enough to pay for themselves and put money in your pocket long term. If you want to reduce your electric bill and your carbon footprint this is a good choice.
These systems allow you to store your solar power in batteries for use when the power grid goes down or if you are not on the grid. Hybrid systems provide power to offset the grid power whenever the sun is shining and will even send excess power to the grid for credit for later use.
Conclusion: We do not recommend off-grid systems for the average homeowner/handyman. They are not cost effective nor are they easily homeowner installable. You can expect to pay 3 – 4 times the cost of a grid-tied system for a similar off-grid system providing suitable battery power for your needs. We usually recommend installing a standard grid-tied solar system and investing in a standard backup generator for a fraction of the cost. It’s what we did at our office!
