Title: I want to install solar panels
Post by: gedavox on September 14, 2019, 11:01:27 AM
So far, I myself practically do not understand anything about this, but I hope to figure it out with your help. So I built a small house: one room 6 by 6, a small kitchen 3 by 4 and a bathroom with a toilet 3 by 3. I want to install solar panels there. From the technology will only TV, TV set-top box, refrigerator and washing machine. Which battery should I choose? And another question, will I have problems with TV and smart set-top box? Does this affect the image in any way?

Thank you for the information. About the set-top box for TV, I now know everything. But what about solar panels, will someone tell me something?

NO it does not effect any of the appliances but i will rather suggest to contact professional installers and do the magic for you.

This does not affect any of the appliances. I installed stations and turned to SunPower 100W. I chose a company for a long time, looked at various reviews, etc. And how to choose panels at the best price, as well as various components.

We have had a simple system of PV panels connected to an inverter for 10 years. This was 17 x Sanyo (now Panasonic) N235's giving us a output of 3.995kw. More recently we have installed another 26 x Hyundai 400 watt panels This has come with an all singing and dancing system so we can run off grid for 9-10 months a year.

Find out how much roof area you can/want to cover. Not all panels are the same, regardless of what salesmen might tell you. Look at which an Aussie based site for solar saddo's such as myself. You should be able to find real examples of what you can expect in your local area. Factors affecting output are how far south you are, the orientation of your panels, the pitch of your roof and most importantly any shading issues.

Our new Hyundai panels are 1720mm x 1140mm with a small gap needed between the panels. They are shingle panels so should be better able to resist shading. In terms of efficiency the Hyundai appear to be very similar to the Panasonic.  We have only had them 3 weeks. The latest Panasonic panels are about 7% more efficient than mine. There is a trend to larger panels as these can be fitted quicker. However this does often mean wasted roof space.

I always suggest everyone installs as many panels as they can fit because you do not want to go back and do the job again. The cost of scaffolding wiring and an inverter do not vary much.

As a guide, an east west configuration will give you 80% of the output of a south facing one and you will only get 30% of your annual output between the Autumn Equinox and the Spring Equinox.

I do have lots of data.
