Ground mounted photovoltaic system are usually large, utility-scale solar power plants. Their solar modules are held in place by racks or frames that are attached to ground based mounting supports.
Ground based mounting supports include:
Pole mounts, which are driven directly into the ground or embedded in concrete.
Foundation mounts, such as concrete slabs or poured footings
Ballasted footing mounts, such as concrete or steel bases that use weight to secure the solar module system in position and do not require ground penetration. This type of mounting system is well suited for sites where excavation is not possible such as capped landfills and simplifies decommissioning or relocation of solar module systems.

- Q: Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?
- No. The solar panels would never be balanced. Those blades need to be very balanced. Additionally, how would the solar panels get the power from a rotating blade to the ground? It is better to have separate units. What we ought to be concerned with is having large solar panel farms. These are counter-productive to going green, as they still require long and harmful power transmission lines. Solar panels ought to be put on top of buildings which would be using that power. Any additional power not used could be added to the power grid. For those types of clean energy that are not practical on the roof might get space near the building, keeping the transmission lines as short as possible. Large farms ought to be owned by the nation, keeping the cost of the power to the customer as low as possible. Power companies rip off consumers with their price gouging. It is time to let the burden of making a few rich at the expense of the many end.
- Q: 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.
- Q: Can solar panels be installed in a community or neighborhood?
- Yes, solar panels can be installed in a community or neighborhood. In fact, many communities and neighborhoods are increasingly adopting solar energy as a sustainable and clean alternative to traditional power sources. These installations can be done on residential rooftops, community buildings, or even as shared solar projects where multiple households can benefit from a single solar installation. Installing solar panels in a community or neighborhood not only helps reduce carbon emissions but also promotes energy independence and cost savings for residents.
- Q: What do these mean? I'm interested in doing a solar panel project. The problem is I know nothing about electricity, wiring, or panels so I've bought a small panel to experiment with first.I don't know what amps, watts, or volts are; what I should be reading on the batteries I will be charging? Or on the small appliances I will be running?The panel I bought has four settings:. 3V ---- 200mA2. 6V ---- 00 mA3. 9V ---- 50mA4. 2V ---- 50 mA(What is mA?)Also, will you give examples of what I can run with this? Make up any scenarios with whatever amps/volts/watts.
- okorder / to see our solar panel project.
- Q: Do solar panels require a specific type of wiring or electrical setup?
- Yes, solar panels typically require a specific type of wiring and electrical setup. They need to be connected to an inverter, which converts the direct current (DC) generated by the panels into alternating current (AC) that can be used in homes or fed back into the grid. Additionally, solar panels usually require specific wiring configurations to ensure proper grounding, protection against overcurrent, and compliance with local electrical codes and regulations.
- Q: how long till a 50 watt solar panel pays itself off in buffalo, ny if its $500. i have national grid and heres the link to the rates. i am residential.
- I have a small system and do not make enough to sell back (no batteries) so it was less than 7 years BUT when you are talking about putting the initial in to a high yield div account and comparing it then I would say it took only 4 years to pay for because I was invested like many others with the capital it would have taken to get a large system and that investment LOST money while my solar pays for itself every year bit by bit. With systems now more efficient and rebates bigger and the investment alternatives not any better it is an easy choice.
- Q: I know the basics of how solar panels work. Solar panels convert sunlight into DC electricity which is stored in batteries which would need to be run through an inverter to convert it to household AC. But is there a way for the appliances to use the solar panels electricity FIRST and any additional power from the grid? Is that how it works or do they only run specific devices(water heater, pool pump, etc)?
- You okorder /... Click on the box that says schematic to see how everything goes together. You need to talk to your electrical inspector to see what their requirements are for installation. You also need to have a net metering agreement with your electric company to connect to the grid. You are probably going to require a professional solar installer. Her's a list of NABCEP certified installers in your state. :)
- Q: Can solar panels be used to power a waste management facility?
- Yes, solar panels can be used to power a waste management facility. Solar energy can be harnessed to generate electricity which can be utilized to power the operations of a waste management facility, reducing reliance on traditional energy sources and promoting sustainability.
- Q: . Do they scratch easily? How do I remove snow from them without scratching them?2. What does the upkeep of many solar panels consist of? I want to have my electricity completely off of the grid.3. Are all solar panels made from the same material, regardless of size?
- anythign can be scratched/ruined/altered if not tended to properly.... remove the first biggest layer of snow and leave a lil under to try to see first if it melts away on its own (dpeendin what season of course) if not than get some luke warm water and soak the snow.... slosh it off with a rubber shovel or mop.broom whatever wont damage ur panels. anythign you take care of will last longer and take care of you.... and solar is expensive to put in and can be expensive to maintain . depends where you have most sun and depends how many resources you use, if you leave the tv on absent mindely all night and take 50 min showers or blast the heat with jsut on epathetic lil donwpour of rain instead of just BUNDLING UP like a alot of lazy *** ameicans and.or rich careless bastards of course youa re goign to be paying up and out of your asshhhhh-hooooo and nooooo there are some different materials solar panels are made of, there is a main base/core they use but im sure there are AT MOST two...the rest is either glass or plastic! depends for what you want and how many , includign size.... good luck!!!! excuse my typos
- Q: Can solar panels be installed on drones?
- Yes, solar panels can be installed on drones. This allows them to generate power from sunlight and extend their flight time by reducing reliance on batteries. However, the size and weight constraints of drones present challenges, so the efficiency and effectiveness of solar panels on drones may vary.
