What kind of solar panel would be enough to run my computer on the network 24 hours a day?
In addition to my fridge, the only other I run every electrical device on my computer (CPU, monitor, modem, speakers). So to reduce my hydro bill, what kind of solar panel would be enough to run my computer on the network 24 hours a day? Thanks Wow, Thanks guys. So check out local prices for the panels solar. It cost me about $ 5000 to have 1000watts of panels installed. With my current hydro project, which pays every other month, would have to wait approximately 27 years before breaking even with the purchase of $ 5000. really not that easy for us to save the planet ..
In round numbers, say you have a power supply of 500 watts on your computer. That sounds pretty average. Now maybe most of the time the computer is not using all 500 watts, but this is how much the power supply can deliver when needed, so we must design a solar system that can accommodate a lot too, so it's not the weakest link in the system. You need 500 watts for 24 hours, or about 12 kilowatt-hours per day. Of course, its solar cell will not to work for part of the day when the sun is down, so you have to be charging a battery + driving the team, while the sun is up. To keep the round numbers, say you get sun for half the day. Then, the solar system has to provide 12 kilowatt / hour in just 12 hours. Basically, you will need a minimum of 1000 watts worth of solar cells. A sample of solar cells (URL below) is 11.5 "x 14.75" and offers 11 watts. That would be one watt per 15 square feet of solar cells. It needs 15,000 square feet of solar cells for its 1000 watts. That would approximately 10 'x 10'. Of course, the number of 11 watts is probably just what you get in ideal circumstances (such as the sun shines directly on the cell, under conditions of no pollution and no clouds, etc.). The circumstances are rarely ideal. So you probably want to add a fudge factor to compensate for it. Maybe twice the size of the solar cell 10 'x 20'. Maybe now you live in northern Alaska, for example, in which only receives sunlight at all during the winter, but the sun all day in the summer. That probably would not change its solar cell lot, but would need a larger bank of batteries for all of winter. You can see that there are plenty of factors to weigh. Maybe if you're going to spend a fortune building a solar system, could shell a bit more energy extremely efficient computer.
