Q:how to build a solar panel?
Can you show us how to build a solar panel ?
Q:What kind of batteries to use for a solar panel?
Deep cycle, Golf Cart Batteries. You can get them at a battery store.
Q:Advantages and Disadvantages of using solar panels?
benefit: 0 value for the source of power No by way of product draw back: Unreliable extreme value to purchase image voltaic panels. Now once you're speaking approximately actually in basic terms utilising image voltaic power i.e. letting water sit down outdoors until the solar warms it up... Then I see no actual benefit to it as a results of fact it will not at all have the skill to warmth water on your needed temperature and it will take way too long.
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.
Q:I'm have a DIY solar panel and wanted to use micro inverters?
It won't work for several reasons. ) Enphase needs 24V modules, you made 8V ones. The voltage is too low to turn it on. 2) Only UL listed (or similar lab) panels are allowed to be connected to your house electrical system. Even if you did get them to work with the Enphase, you won't be able to get the system inspected, there is no way it would be allowed to be turned on by the electrical inspector nor the electric company. 3) If you got by obstacles and 2, and you had an electrical fire in your house, it is highly likely your insurance company would not pay you for it, as you used non-UL panels. DIY panels are fine for little back yard projects, but when it comes to your home, buy real ones. The price has dropped so much in the last 2 years, it's not worth it to mess around.
Q:adding more solar panel & battery?
If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). Not exactly. Assuming the black panel establishes an equilibrium temperature, it's going to be losing exactly as much heat as it's receiving during the day. Some will radiate out into space, some will conduct or convect into the atmosphere. As a wild guess, maybe 50/50. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The panels are only about 4% efficient, so it's the same situation as the pure black panel for 86% of the energy. The remaining 4% will get stored in the batteries and then converted to heat at night. That heat will eventually leak out of the house and warm up the Earth a tiny bit. I think it's much the same situation either way. With the black panel the energy gets radiated / conducted/convected right away. With the solar panel a small percentage is stored and not so much is radiated, mostly conducted and convected. You're partly right as a black panel is going to radiate more into space than a house. But you're taking about maybe some day about 4% of % of the differening radiation/convection/conduction fraction, of the Earth's surface area. Probably not significant.
Q:How Do solar panels work?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q:How efficient are the solar panels....?
DS's solar panels convert 22% of their available energy into electrical power. This may not sound very good, but it is much better than most solar panels. Most solar panels on people's houses, for example, are fairly inefficient. Less than 4% of the energy that reaches them will be converted to electricity. DS's panels are so efficient, in fact, that unless the ion propulsion drive is running, DS is producing far more power than it needs.
Q:would the planet cool if covered in solar panels?
The opposite - they heat the Earth up. The ground underneath might be brown or green or sand. The solar panels are Black. They absorb more radiant energy. Solar electricity is energy and somewhere down the wire will produce heat. Solar's saving grace is that it has the same heating effect year after year. But greenhouse gasses have a cumulative effect. The excess gasses produced in year one are added to the gasses in year two, etc. For instance say the heating of soalr cells is 5 times (5s) that of greenhouse gasses (g). Year - Total Heating - 5s + g 2 - 5s + 2g 3 - 5s + 3g 4 - 5s + 4g 5 - 5s + 5g 6 - 5s + 6g 7 - 5s + 7g 8 - 5s + 8g 9 - 5s + 9g 0 - 5s + 0g etc... In 50 years you have 50 - 5s + 50g
