[QUOTE="bladerunnerpv, post: 544785, member: 35385"] You're welcome. 12x395W panels in SSW, 30deg tilt, in S.E. England suggests about 4500kWh generation in easy-pv. The inbuilt usage profile indicates about 3300kWh would be used directly, with the rest exported - in summer months at peak generation you may not be able to consume all the available PV in daytime, but your daytime usage profile may be higher than average as you wfh - kettle, PC, screen etc. I'm not aware of any (free) tools which have different or customisable consumption profiles, it would be handy to be able to import smart meter usage history for example. In PVGIS you can select different years irradiance profiles IIRC to get a feel for variability in PV generation. Higher wattage panels are available ~600W, they are heavier though, need suitable inverter as they can have significantly higher Isc or Voc, compared to 400Wish panels from what I've seen, and are not necessarily as good efficiency-wise for converting irradiance to kW. The optimum is to get as much kWp per meter squared on the roof as poss., sometimes you can fit more narrower panels, you just need to do the sums and balance the costs. An immersion diverter may also be worth considering, it sends spare PV to heat the water. [/QUOTE]
