Q: I have a 2 volt deep cylce Everstart battery with 845 cranking amps, and a Grape Solar GS-S-250-Fab5 250-Watt Monocrystalline Solar Panel . I use them to power a 48Flat screen TV, a Roku, my 65 watt consuming MacBook Pro, and a 65 watt Fan.I know from previous experience that just the battery, an inverter, and the fan, that the fan will blow for 0 hours straight.Should I really be concerned with a Charge Controller?: Should I really be concerned with a Charge Controller? Yes. The main purpose of the charge controller is to protect the battery from over charging. Over charging reduces battery life. And spending extra money for a MPPT type controller will get more more useable power out of your solar panel. Would another battery of the same magnitude be helpful in preventing an accident? How much storage capacity does your current battery have (measured in kWH)? A ~$20 Kill-a-Watt meter would take a lot of uncertainty out of how much power you actually use. Even deep cycle batteries suffer reduced battery life from deep discharges. The battery sounds too small for the loads you describe so I would think you would want more. ---------------------------------------... After reading the other answer In a nutshell, with your small 2 volt starting battery, 24 volt panel and a mix of unknown loads, (which is correct), I thought I would elaborate. I had not considered the possibility that you bought a 24 volt panel for your 2 volt battery. Hooking the panel you bought directly to the current battery is a horrible idea. I you were lucky it would just cook the battery in a short period of time. You basically bought the wrong type of panel for a 2 volt system. I assume that there are no controllers on the the market for this situation. If that's the case, I don't know of any good way match the 24v panel to the 2 volt battery.

Q: Can solar panels be used in areas with high levels of humidity?: Yes, solar panels can still be used in areas with high levels of humidity. While high humidity can affect the efficiency of solar panels to some extent, they are designed to withstand various weather conditions, including humidity. However, it is important to note that regular maintenance and cleaning may be required to ensure optimal performance in such environments.

Q: Can solar panels be installed on an agricultural greenhouse or nursery?: Yes, solar panels can be installed on an agricultural greenhouse or nursery. In fact, it is a popular practice in many agricultural settings. Solar panels can provide renewable energy to power the greenhouse or nursery, reducing reliance on fossil fuels and lowering energy costs. Additionally, the panels can be mounted on the roof or ground around the facility, making efficient use of available space.

Q: Can solar panels be used in areas prone to hurricanes or earthquakes?: Yes, solar panels can be used in areas prone to hurricanes or earthquakes. While these natural disasters can pose challenges, solar panels are designed to withstand extreme weather conditions. They are built with durable materials and undergo rigorous testing to ensure their ability to withstand high winds, heavy rain, and even minor earthquakes. Additionally, proper installation techniques and maintenance practices can enhance their resilience in these areas.

Q: How long does it take to recoup the cost of solar panels through energy savings?: The time it takes to recoup the cost of solar panels through energy savings can vary depending on several factors such as the initial cost of the panels, the amount of energy they generate, and the cost of electricity in your area. On average, it can take anywhere from 5 to 20 years to recoup the upfront cost. However, it's important to note that solar panels have a lifespan of 25 to 30 years, so you can continue to benefit from energy savings long after recovering the initial investment.

Q: Can solar panels be installed on historical landmarks?: Yes, solar panels can be installed on historical landmarks. However, it is important to ensure that the installation is done in a manner that preserves the historical integrity and aesthetic value of the landmark. This may involve careful planning, consultation with preservation experts, and using discreet or integrated solar panel designs.

Q: Are solar panels fire hazards?: Solar panels themselves are not fire hazards. However, if there is a faulty installation, damage, or improper maintenance, there is a slight risk of fire. Regular inspections and adherence to safety guidelines greatly minimize this risk, making solar panels generally safe and reliable.

Q: Why should I have a Generator if I have Solar Panels.....?: There is now a completely portable (and ultra-high efficient) solar power generator which produces up to 800 watts of household electricity on demand when you need it most. News of this solar backup generator (it's the first off-the-grid breakthrough in 50 years) is spreading like wildfire all across the country!

Q: Can solar panels be used to power a space station?: Yes, solar panels can be used to power a space station. In fact, many space stations, including the International Space Station (ISS), utilize solar panels as their primary source of electrical power. These panels convert sunlight into electricity, providing a sustainable and renewable energy source for the space station's various systems and experiments.
