FAQ

I want to be more self sufficient and get solar panels for electricity in a small house any tips will help. i need to know how many watts is enough and ect.
With a small house it may not be necessary to put solar panels in it. The wattage that is needed will not be much of a difference when using electricity.
What direction do solar panels usually point? North? East? South? West?
South in the northern hemisphere. - this gives you sunlight on the panel a major portion of the day without the need for a mechanism to follow the sun or change direction from E to S to W as the day progresses
So I want to go completely solar. Do I need the connected solar panels alone for after sundown hours; Do I need something else in order to have energy to run my entire house throughout the night?In other words do solar panels store the energy for after sun-down or do I need other devices to store the energy?
solar panels don't store energy, they only generate it. If you want to store energy you need a battery bank of some kind to get you through the night and anytime the sun isn't shining. If you have a little extra in the budget you might look at a geothermal system for your home's heating and cooling needs. They're highly efficient systems and you can supplement however you like. Whatever you do, though I hope you have a good building envelope in place already. Solar panels are cool, but if you have a leaky house, you're still not getting the best out of your panels. Do the more mundane stuff first. Insulation, windows, and weather-tight doors.
I don't have a regulator connected as they are a little expensive for a pensioner, If I join the panels into line to the battery bank from the roof should that be OK.?
You can do this, but it isn't the best way to go. There is no problem with joining the solar panels. There are two ways to do this, in series and in parallel. A series combination will add the voltages that each panel is producing together, but not the amperages. For example, if five panels are producing 6V at 300mA each, the end result will be 30V at 300mA for a series array. A parallel combination combines the amperages of all the panels, but not the voltages. So, in our earlier example, five panels at 6V and 300mA would provide 6V and 500mA (.5A) if wired in parallel. Series-parallel combinations are also possible, giving some of the benefits of each method. This would probably better understood by doing a quick search on Google Images for series, parallel, and series-parallel. You CAN connect the solar panels directly to your battery bank with no regulator. Unfortunately, without a regulator, the connection is two-way. When the sun is out and the solar panels are producing more voltage than the batteries, the batteries will charge. However, when the panels are producing less voltage than the batteries, the batteries will instead send power into the solar panels, which will be dissipated and wasted. The panels may charge your batteries during the day, but they will discharge them at night.
Yes, solar panels can be used to power a data center. Solar panels convert sunlight into electricity, which can be used to power various devices and infrastructure, including data centers. By installing a sufficient number of solar panels and using energy storage systems, a data center can be powered entirely or partially by solar energy. This can help reduce reliance on traditional power sources, lower energy costs, and promote environmental sustainability. However, the feasibility and efficiency of using solar panels for powering a data center may depend on factors such as the location, size of the data center, and the availability of sunlight.
I had installed over the summer a solar panel system on my house. Hers some infofor you: I live in MOThe system cost 25K (Rounded numbers)The Rebate from the utility company was about 0KThe expected tax rebate will be about 5KI have a home office from which I work and is 5% of my homes sq footage. My question is though I am getting a basic tax rebate, should I be able to claim part of this off as an expense for my home office?It seams logical since I used to deduct part of my electric bill and I there for should be able to write off part of this. I am, after all using electricity and getting a bill from the utility that is higher than it would be if I didn't have the office2. If so which amount should it be? The full 25K or something after the rebates.
5% of the Net Cost (After Rebates) Depreciated over 27.5 years. EDIT: Oops ....39 years. I was actually debated that in my head before I posted.
Solar panels are suitable for a wide range of climates, but their efficiency may vary depending on the amount of sunlight available. While they can still generate electricity in cloudy or colder regions, they perform best in areas with high solar insolation and minimal shading. Advances in technology have made solar panels more adaptable, allowing them to be utilized effectively in various climates around the world.
Hi, i want to please a solar panel in Lima Peru, my Latitude is -2 and longitude -77. I understand that since i am in the southern hemisphere, my panel should be pointing north. However, i am using a program called pvdesigner, and according to this, y should face my panel with and azimuth of 00degrees (0 = south) and a tilt of 60degrees. Does this make any sense?thanks
It doesn't make sense to me. I am at latitude 37.7,and my panels face south at about 38 degrees. Yours should be pointed north as you suggest. Being so close to the equator, and in the absence of any better information, an angle of 2 degrees would be appropriate. However, choosing the best angle will greatly to your overall efficiency, so I would try to find a more credible source, How about the folks from whom you buy the panels. They would know precisely. By the way, if you haven't installed the system yet you might consider going to a high voltage system to cut known line losses in the conductors between the panes and the inverter, I did that plus increasing the conductor size over that recommended by the manufacturer. I gained about two percent in efficiency
