DIY energy: UK solar inventions could reduce bills

Any news worthy story. Good things to watch at the Cinema, Theatre, on TV or have you read a good book lately?

200 Watts here would cover the base for the house most of the day and a strategically placed small panel with tracker would probably achieve that in many conditions.

I'm finding with my set up at the minute that strategically placed small panels are giving better returns than larger systems in marginal conditions.

The problem is that there simply isn't very much sunlight from which to extract energy! Nothing can escape that fact.

In bright-overcast conditions then a horizontal array does best, when the sun does shine in winter the angle will be low so a steeply-angled array is best. However most of the time your array could be pointed wherever you like, it still wouldn't generate anything of use, so the: complex, expensive, failure-prone, tracker, would make precious-little difference.

Based on Nowty and Stinseys replies I agree with you JB - larger mounts aimed by the Mk1 eyeball and directed using simple Mandrolics :D

Who knew I had already partially solved that issue :lol:

You and Stan had similar ground mounts? I liked the look and it's pushed me to make one string of 3 skidable. I'll be looking for seasonal moves not daily so rough and cheap for me. :D

That's a decent amount of power Iain! Over 1MWh in the 'off' months, nice! You are 41.85kWp and i am 24.88kWp for Feb. Huge difference, right I'm moving the house up besdie you!

Just shows the effect overspeccing on Size can have (& location). TBH, I'd keep going and have another 2kW on my roof and damn the expense but swmbo has been very understanding to date and I won't abuse that. :)
