Talking to a friend today about his rather low return on feeding solar to the grid, I was wondering if it is possible to get a small system installed (200-400 watts so only a couple of panels) for the sole purpose of offsetting the power consumed during the day? Wait hear me out..
In my scenario, we work from home running our own business. We would easily consume around 400+ watts of power per hour running our computers, test equipment, TV, lighting, making lunch etc during the 'full sun' hours of the day. I'm not interested at all in buying extra panels to feed into the grid for lacklustre returns, but would be quite interested if that first few hundreds watts of power could be offset.
But does any solar installer actually accomodate such a small system? Say 1-3 panels plus inverter.
I understand that depending on the day, cloudy days, winter, bird poop on your panels, neighbour's overgrown trees will depreciate the output. In fact I used to run a mini system just to power my NAS 24/7 as a practical thought experiment. However I was limited in placement of my 200w panel as it became grey if I could install it on our roof myself (for insurance etc).
Anyway, what might be the collective groups' thoughts on this? Am I missing something quite obvious (apart from a possibly stupidly high install fee?)
Many thanks! Look forward to reading replies!
- Fun and useless fact: Did you know that the phrase 'Ahoy hoy!' was first suggested by the inventor (or should we say the person who got to the patent office first) of the telephone Alexander Graham Bell as the defacto greeting for using the telephone? Now you have a useless fact to pass on to your peers, friends and family! Or perhaps to drive them away….
