Very nice and clear!!

What about a rectifier as most things use 12 watt to power them and solar batteries so I power all things with batteries nearer all things to reduce losses and you will need a technician to take out the ac adapter out so my tv uses 21 wH one solar battery powers the tv for 4 hours my fridge use 3 batteries trough to night and 5 batteries during to day I also use alarm batteries for lights which are 6 w so ten batteries for the lounge and two for every other room that also catteries for charging cellphones using a rectifier to exactly what your phone needs

thank you so much for sharing this video.. its very interesting and very informative.. keep it up..
-
where did you get your heat, dirt, and wiring loss numbers from?
-
Great video. In addition to issues already raise about the math, to compensate for 40% loss you need to divide 8200Wh by 60% which equals 13667Wh. Not 11480Wh. So when you remove 40% from 13667Wh you get 8200Wh.

I knew a guy in the states who walked me through his set up. I literally was at his house. Here's what he did. He had a metal freight container on the side of his house with 12 forklift batteries inside it. Each forklift battery hooked to each other with cables and they ran to a digital read out on the the freight container wall. He used to produce enough he sold back to the electric company. He never paid for electricity from the electric company.I think he had 24 panels on his rooftop. Might have been 12?

Great. And by the way I also recommend this. It's step by step guide how to create your own power at home. See more here https://plus.google.com/117080406396814357120/posts/AyfoTMzttTJ

Thanks for your clarity!

Hi Martin! Great tutorials! Appreciate the power usage calculation suggestions! Just a thought about the overheating effects of the solar panels - would it be helpful if one could either a) redirect the cooling air from a heat pump to help cool off the solar panels or b) Temporarily place for example a 30% shade net or similar cover in place to minimize the overheating effects that one may incur? We live in Potchefstroom and during the summer months - November to March we have average temperatures of between 15˚C and 29˚C and in Winter - May to August we have average temperatures of between 2˚C and 18˚C.

hi,
i am currently doing some computation for my home (to be built) and i ended up looking at 5kw inverter. i am planning to go hybrid while doing best effort not to push electricity back to the grid (as much as possible).
since financing is a concern right now, my initial plan is to lay all the pv first and plus using an all-in-one inverter/with built-in battery charger. this is so, so if time comes that i'd have enough cash, then i can add the batteries, then next would be the generator (the generator will be auto initiated by the inverter).
at the moment, i am not sure what good brands that are available market currently, that addresses my requirements. and... this is the part where i listen to your valuable input.
many thanks,

Hi there, I a bet confuse about how to calculate my needs from off-grid solar syetem, by the end of this year I want to start my farm in South Sudan and I want to use several electronics items such tv, ps3, small forge , dish receiver, computer and self phone.
I want you to advise me how much kw I will need to have.
Thanks. -
good educative video... thanks
-
great videos thank you, I would like to ask a questions. wouldn't running off batteries exclusively, and have the sun recharge batteries during the day be a viable solution as you would get consistent power as opposed to all the fluctuations that come with clouds, changing sun position etc.
-
thanks for sharing
-
I would really appreciate a generic spreadsheet that you may have created.
-
The above calculations to the sun every day is good, but the actual experience for several days of bad weather, how to calculate?
-
Treasure trove: Here. Thanks for the great intro.
-
This is Great stuff! Well done...
-
These tutorials are awesome. I want to incorporate a wind turbine into a system not unlike yours also to assist with charging the power bank. and a back up source of energy.
Would this be possible?? -
I have a 120ah battery and a 124 watt panel, it wont power my 70 watt flat screen tv though, only router, phone charge, 1 cctv camera. thanks
