- Q: I've seen a couple homes around my town that have solar power and I live in the Desert, where the sun is shinning and it gets really hot during the summer. We run our air conditioner a lot making our electricity bill high.So I just wanted to know if anyone has or knows anyone that has solar panels? are they worth getting and is it the same as having electricity?
- and, if given the tax credits, you'll see a faster return on investment in CA than I would have in Western PA (I was given a 0 year return number without factoring any tax credits). Plus you'll be doing something good for the environment. My brother put his house for sale which had solar panels for hot water, and was offered good money for the solar panels independent of selling the house. If anyone has a any no answer that doesn't involve the initial expense, I'm looking forward to reading it.
- Q: On how to connect a solar panel to a battery and then to a lightbulb,the project is offgrid..
- Build okorder
- Q: in the afternoon sun heat increases to high level due to which the panels heats up very high now my question is this heat will effect the panels life time and will damage the panels or not ??
- Most experts believe solar electric modules have a lifespan of at least 25 to 30 years and most manufacturers provide a warranty for this period. However, the truth is that we don't really know for sure since most modern solar panels have not been in existence that long. Many experts believe the actual number could be much higher, possibly as much as 50 years. What is very clear is that solar modules are extremely durable and lose very little of their energy generating capacity over time. From: bit.ly/tpTfK
- Q: can this amount of solar charge these batteries.
- you need to have a voltage regulator on the gadget. That suggested, i imagine you're literally not giving it sufficient time. The battery might want to convey the voltage all the way down to its element. it is merely you attempt to replenish a huge reservoir with an eye fixed dropper. Bringing the voltage down would not help both. That lowers your ability.
- Q: I have 2 20 watt Solar panel. I have it hooked up to solar controller and batteries to inverter. Am trying to figure out how much watts am getting. I found the voltage but how do I find the amp reading on a mutimeter?
- It is possible your meter does not have the capacity to safely measure more than 300 milliamps which is too small to measure current output from solar panels. Assuming no losses in the system or components, if your meter does not have the capacity to measure 0 Amps, you will need to get one that does. Analogs are better than digitial for this. Most often the 0 Amp circuit of the meter has a discrete positive plug location for the positive test lead. Most have a common ground connection with the rest of the meter functions. If you are measuring current at the battery in the charge mode- Negative lead of meter goes to positive terminal of battery and positive lead of meter goes to the cable that was connected to the positive terminal of the battery. Since the Wattage is a nominal measurement, if you measure between the panel and controller, take measurement on one leg of the panel, as you want to measure the current with the loaded active circuit. Meter is oriented the same way as the measurement at the battery would be made above only this time the meter is between the panel and controller. At peak solar conditions, expect current to be measured at 2.5 to3 Amps or more per panel. Under optimal conditions your panel will have higher output than their ratings indicate. Open circuit can be close to 20 volts. Never short circuit the output of the solar panels. It is volts multiplied by amps that gives you Watts.
- Q: How do solar panels affect the property's overall cost savings?
- Solar panels can significantly impact a property's overall cost savings by reducing or eliminating electricity bills. As solar panels generate electricity from sunlight, they offset the need for grid power, resulting in lower energy expenses. Additionally, excess energy can be sold back to the grid, further increasing savings. While the initial investment for solar panels may be high, the long-term financial benefits and potential tax incentives make them a worthwhile addition to any property.
- Q: I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
- There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
- Q: How much roof space is needed for solar panels?
- The amount of roof space needed for solar panels varies depending on several factors such as the size and type of panels, the energy requirements of the property, and the efficiency of the panels. However, as a general rule of thumb, a typical 1 kW solar panel system requires around 100 square feet of roof space.
- Q: name things someone could use solar panels for or make with solar panels? (use solar energy i mean?)
- Solar panels can produce enough energy to run your average size unit (depends on panel size). It cost you bit more but its for once in all, average panel age limit is above 20 years (approx) so it can save you a lot, also environment friendly. Basic Panel can support your lights which are mostly used in any premise, even your TV, computer and stereo system. Is that enough to save and entertain you?.....Think so.
- Q: My dad owns a restaurant, and we are doing farely well, but we were thinking on installing solar panels to minimize electricity costs (and of course make it greener). My dad would like to hear some numbers on the price in today (August 29/202) and savings he could possibly make over the years. So In Total Here's What I'm Asking:) Would it be hard to install?2) Maintanence?3) Monthly Expense? (None?)4) Price?5) Savings over time?6) Pros/ConsThank you so much!
- not really 2 little 3 very little 4 depends on size of unit 5 depends on how much electricty you use 6 many
