Is your property suitable for solar?

As part of our comprehensive FREE survey and quotation, we will guide you through the requirements of solar pv.

Structural Analysis The load bearing ability of your house, the pitch of your roof and it’s ability to deflect wind are all major factors to determine the suitability of your house. It’s not uncommon for a property to require minor strengthening before we’re able to fit solar panels.

Shade Analysis We conduct tests to ensure the maximum amount of sunlight is absorbed and how much shade your house experiences during different times of the day and year. This can affect which hardware we recommend and allows us to calculate potential output and savings.

System Recommendation Based on the data our survey reports, we’ll be able to recommend the best system for your property. This will include the cost of the system, it’s specification and projected break-even timeframes.

Level up your solar installation with battery storage

By its very nature, any electricity generated by your solar panels must be used, sent back to the grid, or stored for later usage. If your household doesn’t utilise electricity during energy producing hours, your best upgrade would be battery storage. Although some energy providers will give you a small sum of money for any energy you send back to the grid, this usually equates to less than half the cost to buy the same energy back from them! With a battery storage system from Big Green Solar, you’re able to harness the energy your panels generated at times that suit you.
