SW3 advised on a solar PV installation suitable for our roof. Although South-facing, there are trees either side of the house which means that sunlight is not even across the roof. SW3 set out a number of different system options, comparing optimisers with micro-inverters. They also proposed battery storage to match our typical usage and using a GivEnergy battery compatible with Octopus smart tarrifs. The proposal process was helpful, with a few tweaks made along the way in response to questions and comments. SW3 were significantly more expensive than other quotes, but we felt that they had taken care to propose a suitable solution for our usage and the challenge of shade from trees. Delivery could have been a little better planned, in particular identifying the need to store bulky equipment overnight in our garage, something that we have discussed with SW3 to give them constructive feedback on that element of the planning process. The installation was very neatly completed. A separate visit, a few days later, was needed to commission the battery as it took some tweaks to our WiFi to get this to reach the garage. Again, it wasn't clear in advance that we might need to take action. Overall, we're happy that we had a carefully designed system proposal and a neat installation. We're confident that this young business will take our feedback on board to smooth out the planning process. So far, we're generating about 50% of our power through the autumn. We look forward to seeing how the system performs in summer.
