### Solar

Explained

### How many panels can you fit?

### When we design your solar system a few key factors are your annual electrical bill, the overall size of your roof and determining the amount of shading on the roof. The roof space will tell us how many panels we can fit on it, thus determining size of the solar system in kW. Shading analysis will give us a more accurate system performance estimate. The size of the system will determine the price reduction on your current electrical bill.

### *The system estimates described below are based on our 10x 360W panel (3.6kW) system with and without a 2.6kWh battery. The estimates below may differ from where you live. We have assumed your roof is south-facing, has zero shading and has the size and structural integrity to install the possible system sizes below. As well, we have included in system performance loss due to soilage on your panels. The performance estimates may differ for your home. The estimated electrical power consumption for each type of property is information provided from UK power networks. For a full report including financial summary please contact us.

The property is expected to consume 3847kWh of electricity each year. Around 33% of this (1274 kWh) is expected to be supplied directly by the solar array. The remaining 67% (2585 kWh) is supplied from the grid.

The solar PV array is expected to generate 4044 kWh over a typical year. 31% (1274 kWh) of the electricity generated is expected to be used directly in the property. The remaining generation (2771 kWh, or 69% of the total) is exported to the grid.

The property is expected to consume 3847kWh of electricity each year. Around 33% of this (1274 kWh) is expected to be supplied directly by the solar array. Another 17% (647 kWh) is supplied from the storage battery. The remaining 50% (1938 kWh) is supplied from the grid.

The total self-consumption is expected to be 50% (1921 kWh) with the battery storage system. Without battery storage it would be 33% (1274 kWh).

The solar PV array is expected to generate 4044 kWh over a typical year. 31% (1274 kWh) of the electricity generated is expected to be used directly in the property. 19% (736 kWh) is directed to the battery for later use, although 90 kWh of this is lost during battery charging and discharging. The remaining generation (2034 kWh, or 50% of the total) is exported to the grid.
