- Q: I have two solar panels that were going to be trashed at work. I want to use them to charge batteries on my RV but i noticed they put out around 20 volts in direct sunlight. So i am wondering: -isn't this way too much voltage for a 2 volt system? -do a need some sort of a regulator connected to keep them from overcharging?
- 20 volts is a common open-circuit voltage for nominal 2v panels. The panels put out about 5v at full load. If the panel puts out little enough that it takes 20 hours or more to put a full charge in the battery you can get by without a charge controller - just keep the cells topped up with distilled water. A charge controller will do a more efficient job, though. The most efficient charge controllers use what's called Maximum Power Point Technology (MPPT) which lets the panels operate at their most efficient point throughout the battery's charging cycle. Available on OKorder. The charge controller should have the same or higher wattage as the panels it controls - if you're not sure of wattage, assume that they are the same as similar area panels you find for sale. Before buying a charge controller, connect the panels through an ammeter to a discharged battery. They may have been trashed because of damage and low output. You need at least an amp for trickle charge, 5 amps for reasonable recharge times.
- Q: I don't know anything about where to buy solar panels. I just want to save on the electric bills.
- that's going to take approximately $forty 4,000 to place sufficient photograph voltaic panels to furnish the comparable quantity of skill which you at the instant have coming from a 220 v a hundred amp skill line on your place. you additionally must understand which you truly want some approach of storage for use at night or dark days. this might upload yet another $7,000 to the fee. the only actual answer for the skill issue is nuclear skill.
- Q: How do solar panels affect the electricity bill?
- Solar panels can significantly reduce or even eliminate electricity bills by generating renewable energy from the sun, thereby reducing the reliance on grid-supplied electricity. When solar panels produce more energy than is consumed, excess energy can be fed back into the grid, resulting in credits or reducing future bills through net metering programs.
- Q: How do solar panels affect insurance premiums?
- Solar panels can have a positive impact on insurance premiums. Installing solar panels may increase the value of a property, which could lead to higher insurance coverage limits. However, the overall effect on premiums can vary depending on factors such as the location, type of solar panels, and the insurer's policies. Some insurers offer discounts or incentives for homeowners with solar panels, while others may charge higher premiums due to the increased replacement costs. It is advisable to consult with insurance providers to understand how solar panels specifically affect premiums in individual cases.
- Q: Can solar panels be installed on golf courses?
- Yes, solar panels can be installed on golf courses. In fact, many golf courses have already embraced solar energy by installing panels on their clubhouses, maintenance buildings, or even on the course itself. The large open spaces and ample sunlight available on golf courses make them suitable for solar panel installations, providing an environmentally friendly source of renewable energy.
- Q: Hi! I bought a Coleman 2 vdc cooler that pulls 9 amps. What size solar panel and amp-hour battery do I need? I only open it 3 times a day. It will hold about 3 gals of milk.
- If it pulls 9 amps continuously, that's 08 watts/hour or about 2.5 kwh/day. If it only pulls half that (does it cycle?) it's about .2 kwh/day. You only want to drain a lead-acid battery 50% or so, so you'll want a 5 or 2.5 kwh battery pack. A typical setup for the 5 kwh would be two L-6 batteries in series, and for the 2.5 kwh you could use 2 T-05 batteries in series. This does not account for days of cloud. If you regularly have cloudy days, size the battery pack for two or three days of use with no input (2-3 x the sizes given above). To charge them, you typically want panels that will charge your battery at least 5% of its capacity per hour (C/20). For 2 volt nominal panels that's 0 amps for the T-05 or 20 amps for the L-6 batteries. It's good to have more than that for battery life (it cuts down on what's called stratification), so you'll want probably 50-200 watts of panels for the T-05 and 300-400 for the L-6. You'll also need a charge controller. Peltier coolers are very inefficient. You'll save money by using a regular mini-fridge and an inverter. Most mini-fridges only draw 50 watts or so, so you're talking 600 watt-hours for a 50% duty cycle. This means two T-05 batteries will give you two days of use and you'll only need 20-50 watts of panel. DK
- Q: Can someone tell me if I can run a air conditioner off solar panel?I have a ET-P65420 20Wp solar panel. What do I need to make it work? I am told I will need a Enphase Energy Microinverter M20. Is that true? I am looking to run a 5000 to 8000btu air conditioner to a max of 0000btu air conditioner. I need to cool a 0x30 space. One time I read, I need total watts of panel to match total watts of air conditioner. Then I read, that I do not and can run more watts then what the panel is depending on the inverter and batteries.Can someone tell me what and how to make this work please? More panes or inverter and batteries?
- You can expect such an air conditioner to use something like 500 - 800 watts of power. The ET-P65420 20Wp solar panel produces at most 20 watts so you will need at least three of them. Since solar cells make DC (Direct Current) electricity, and air conditioners use Alternating Current (AC) electricity, you do need an inverter. The M20 is a 220 volt inverter, and I suspect you are looking at a window air conditioner that will probably use 0 volt power. And the M20 only puts out a maximum of 240 watts so you need one for each of the 3 or more solar panels you will have to use. So the first thing to do is shop for air conditioners, getting the most energy efficient model you can find, paying close attention to the voltage and wattage ratings in the owner's manual or on the UL label on the back. Say it is a 500 watt, 0V unit. You will need three solar panels and three 0 volt model inverters. Also note that the 20 watt rating of the solar panels if when the panel is facing DIRECTLY at the Sun. If you just lay them on the roof, then even if the roof is sloped at a good angle (30 degrees) and facing south, it will only produce the maximum power around noon. 4 hours before noon, unless to go up there and tip them up to face the morning Sun they will probably produce only about half that amount of power. So right there you either need a motorized mount to automatically follow the Sun or twice as many panels. However, if you are going to connect the solar panel(s) into the house power, so that it(they) merely supplement the power company power, then you can use any amount of panels, and the power company will supply whatever extra power you need. That requires a licensed electrician to do. Or if you want to just power the air conditioner directly from the solar panels without any interconnection to the house power, then you need to know a lot more about electricity that you appear to know.
- Q: Can solar panels be damaged by hail or other weather conditions?
- Yes, solar panels can be damaged by hail or other severe weather conditions such as strong winds, heavy rain, or snowstorms. Hail can cause cracks, dents, or shattered glass on the surface of the panels, reducing their efficiency or rendering them completely ineffective. Additionally, extreme weather events like hurricanes or tornadoes can also cause structural damage to the mounting system or dislodge the panels from their position. Therefore, it is important to consider the weather conditions in a particular location and choose appropriate measures to protect solar panels from potential damage.
- Q: Can solar panels be used to power a military base?
- Yes, solar panels can be used to power a military base. By harnessing solar energy, military bases can reduce their dependency on traditional energy sources and enhance their operational capabilities. Solar panels can provide a reliable and sustainable source of electricity to power various facilities and equipment in a military base, contributing to energy independence and environmental sustainability.
