What do you guys think about watercooling cells ? I heard it increase about 15% the efficiency.
Efficiency is inversely proportional to the Temperature in case of Solar Panels. So, Water cooling should definitely give a push on the efficiency. But in the practical case,water cooling these large panels is a messy job. Also, the power required to pump in the water and spray in on top of the panel may nullify the effect of the increase in efficiency. Its good for a hobbyist but may not be practical in a large system. Well according to DIY tutorials and scientific experiments, the power from the pump system is really negligible. It only need to be activated few minutes per day when the sun is high. If I had time and workspace I would totally try.

I'm setting up a small solar powered off-grid system. Will experiment on this cooling technique on it to check how much efficiency gain its giving. Will update here. Before that I need to finalise my solar configuration. I already have an inverter of 1500VA/24V and six 250W/24V Solar Panels. With this I'm looking to make a 400W device run continuously off-grid for 16hrs a day then, on to grid for 8hrs.

Could you update the OP with price details? I'm curious to how this solar panel project will fare price-wise. Doesn't seem like it would do well but I don't know much about solar panel prices so I could be wrong.

It can be anywhere from $.50 to $2.00 depending on if you make your own panels or buy premade ones.

I'm designing my own system and ordered some products. Soon I will have my setup. I will update before that about the plan. Solar Power Systems are expensive and if we are doing it in DIY mode then a lot of costs can be saved. But I'm not recommending DIY solar panel due to many practical reasons. For a small system it may be worth for the setup I'm doing(1.5 to 2 KWh) I can't go for DIY panels.

You above post is not clear to me. I will show you an image below to get a clear picture. Click on the image to get make it bigger. The invertors and controllers connected there are for sample only and are free to change. Also alternate configurations are welcome from all. If you know a good configuration than this for "Working 400W for 7hr backup" and "400W for 8hrs during daytime. Assume the remaining 9hrs the miner is switched off. im having our electrician look at this i will get back to you within 48 hrs Hope you can give the update.

Now I decided to connect the dc devices directly from DC out. My battery setup is 24V and Solar MPPT charge controller out put is 24V DC. Any one know the Antminer S3 input voltage tolerance? I will be converting this 24V to 12V via a convertor which can provide and an output power of 400W.

Sorry, I've been busy but that's cool allcoinminer. Thats exactly what he told me on how to do it, use a charge controller from the panels to a battery and then takes the battery voltage into the antminer through the charge controller. Don't rely on me but I believe the antminers have a higher tolerances because the actual chips run at a lower voltage through their mofsets and don't directly use the 12v. The mofsets probably have a higher tolerance.

So I'm confused? How are you doing it right now? If the antminers are connected directly to the batteries, you can destroy the battery by totally discharging the batteries. Also, the charging of the batteries must be slower than the output it can handle with the charge controller. The charge controller would bypass the battery if it had enough 12v and directly power the antminer.

What is the setup parts? I'm assuming a 24v panel with 24v (hopefully 15a charge controller)? 24v lead acid batteries, and a 24v relay?

When I get time I'll make a full blown guide for solar panels because there seems to be enough interest in it....

Are you buying these solar panels wholesale or retail cause to me right new solar energy is costly and take like 10 years to make back your savings which they should be cut down to 5 years would be nice.
