- 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: Can solar panels be used on boats or RVs?
- Yes, solar panels can be successfully used on boats or RVs. In fact, they are increasingly popular for these applications due to their ability to generate clean and renewable energy while on the move. Solar panels can provide power to charge batteries and run various onboard devices, making them an excellent choice for boating and RV enthusiasts seeking energy independence and sustainability.
- Q: Do solar panels require a battery backup system?
- No, solar panels do not necessarily require a battery backup system. Solar panels generate electricity from sunlight, but without a battery backup, the excess energy produced during the day is typically fed back into the grid. However, a battery backup system can be useful in areas with frequent power outages or for those who want to store and use the solar energy generated during the night or when the grid is down.
- Q: Exactly How much power will this kit produce? for example. Will it only be able to power the 2 light throughout an entire day or would it be able to power a couple TV's with a couple lights. Or a Refrigerator? washer dryer? I'm just wondering exactly what it will be able to do and if it's worth paying $200 for if it'll only power two lights. Don't get me wrong, That's great and will make a difference but i'm looking for something that will make a little bit of a bigger difference. Would the 80 watt monocrystalline solar panel be much better? if so, what would it be able to power? double?

- Q: Can solar panels be used to power a film set?
- Yes, solar panels can be used to power a film set. Solar panels generate electricity by converting sunlight into energy, which can be used to power various equipment and lighting systems on a film set. This eco-friendly and sustainable option can help reduce the reliance on traditional power sources and minimize the environmental impact of filmmaking.
- Q: Can solar panels be installed on a condominium or apartment building?
- Yes, solar panels can be installed on a condominium or apartment building.
- Q: Do solar panels require regular maintenance?
- Yes, solar panels generally require regular maintenance to ensure optimal performance and longevity. This includes periodic cleaning to remove dirt, debris, and snow, as well as checking for any possible damage or malfunctioning components. Additionally, regular inspections and maintenance by professionals are recommended to identify and address any potential issues or inefficiencies.
- Q: Can solar panels be used to power outdoor lighting?
- Yes, solar panels can be used to power outdoor lighting. Solar-powered outdoor lighting systems typically consist of solar panels that collect and convert sunlight into electricity, which is then stored in batteries. This stored energy is used to power the outdoor lighting fixtures at night or in low-light conditions. This sustainable and cost-effective solution eliminates the need for traditional electrical wiring and reduces energy consumption.
- Q: How do solar panels affect the property's overall cost savings?
- Solar panels can have a significant positive impact on a property's overall cost savings. By harnessing sunlight to generate electricity, solar panels can reduce or even eliminate monthly electricity bills. Additionally, excess energy generated by solar panels can be sold back to the grid, providing an additional income stream. Furthermore, solar panels can increase the value of a property, making it more attractive to potential buyers. Overall, solar panels contribute to long-term cost savings by reducing reliance on traditional energy sources and providing a sustainable and cost-effective energy solution.
- Q: Can solar panels be installed on residential homes?
- Yes, solar panels can be installed on residential homes. They are a popular and effective way to generate renewable energy for households, reduce electricity bills, and contribute to a greener environment.
