My husband and I wish to put together a battery bank and solar array. We're not sure where to begin in researching the kit. Being in a remote mountain location, with a 5kW incoming mains supply which would cost a fortune to upgrade, but enjoying a very low unit price for electricity at...

I'm wanting to install a system of maybe 3kW peak panel output, location is northern Spain. We are grid-connected, but the solar system will be off-grid because it will be too expensive and complicated to connect it. In summer, the power will be used to drive the air-con system, which has an...

I understand that microinverters allow each panel to be optimised on output, independent of shading of other panels in the array. What I don't see is what happens afterwards. If each panel puts out a bit of 220V AC, do these outputs all need to be bundled back to an AC/DC battery charger and...

I still need some of the basics here, too many gaps in my knowledge and I don't know the terms I'm looking for. I want to create a solar system to operate my (wood-fired) spa pool, an island system because I don't want the complications of a grid-tie. In simple terms, when the panel power...

I'm designing an island system to run my spa. It's a panel-led design as I can absorb all the energy produced, I need a roof for my log store and the size I an make it is limited by the property constraints. The panels I'm looking at...

I've been kicking around ideas for a pv array, driven largely by the fact I need to roof a log store and pv panels are about as cheap as any other roofing material. But the onward equipment is costly and the complexities considerable. Realising that in the end, the main use I had for the power...

I thought I could find my way around a solar system design, but I'm utterly baffled now as to how it would work. I am planning a wood-fired spa pool. I want to provide power for the 80 watt filter circulation pump for several hours a day. I need power on hand to run the 1kW jet pump motor as...
