- Q: Do higher watt solar panels last longer, efficiency-wise? 3 installers gave me quotes with 3 different sunpower panels. The 225, 25, 20 watt panels. Whats the con and pro's of the different wattages?
- Power from solar panels depends upon its proper installation and the brightness of the Sun.
- 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.?
- Two things on a regulator: a) It will optimize the charge to the batteries - and thereby distribute the most possible power to your active circuits during the day. b) It will prevent the power from the panels from boiling (no kidding) the batteries - no small thing as they are the second largest investment you have after the panels themselves. This is much more critical if you have sealed or Zero-Maintenance batteries. I strongly suggest that you get a regulator as it will significantly lengthen battery life. Follow the directions on the regulator for optimum input voltage and it will let you know whether all the panels should be in series, parallel or series/parallel. But cutting to the chase, you can certainly gang up panels as needed.
- Q: Can solar panels be integrated into buildings?
- Yes, solar panels can be integrated into buildings through various methods such as rooftop installations, solar facades, and building-integrated photovoltaics (BIPV). These approaches allow for a seamless integration of solar panels into the building's structure, providing renewable energy generation without compromising the overall aesthetics or functionality of the building.
- Q: Can solar panels be installed on art installations or sculptures?
- Yes, solar panels can be installed on art installations or sculptures. In fact, incorporating solar panels into art installations or sculptures is becoming increasingly popular as it allows for the generation of clean and renewable energy while adding an aesthetic and functional element to the artwork.
- Q: i don't know very much about it, but can you somehow take off the little solar panels off of the outdoor light things and make it so you can hook an outlet up to it and plug in to it like a phone charger for electricity.
- Little solar panels on lights are very low power. The battery in one such may be 0.5 Amp-hours and .2 V ; it may be different but it should be marked on the panel/battery/manual. An outlet in your house is designed to run on 20 V (typically in N. Am.) and they run on alternating current (AC) whereas the panel generates direct current (DC). (If you don't know the difference, do not worry to much but just understand that they are not directly compatible.) You therefore need an inverter to change DC to AC (and lose some although inverters are now very efficient). But the amount of power generated by those panels is still very small. That is why solar lights are low power (just a few watts in most cases). To make things even more irritating, phone chargers do not work off 20 V AC as you are charging the battery and need a low voltage DC -- which is what the solar panel is giving you. It is almost certain that the voltage from the panel will be less than the voltage required for the phone. The charger is mostly cable but there is a black box incorporated and it should say what the voltage and current output are (the input will be 20V). So you should be able to overcome this not by hooking up the panel to a 20V outlet and then plugging the charger in but by hooking up the panel to the phone directly if you can get enough voltage out of the solar panel (or hook up several) and if you fashion a connection device. They already make them -- solar battery chargers and I am sure you can enter that into a search engine and find loads. Typically the panel alone is much more than a solar light -- which shows the relative power requirements.
- Q: Could anybody give some review about Homemade Solar Panel.
- Low cost solar panels are also extremely popular worldwide and China is a country that has been discovered to be excelling in this field as they manufacture the most economical solar panels when compared to any other country. Looking at the way things seem to be moving it seems that China will soon become a country to contend with because of their capabilities to manufacture things at extremely competitive prices. This fact is quite transparent for the simple reason that China appears to be getting more than double the number of orders. This can also be attributed to the fact that in spite of their low costs they have not only maintained but also improved on their quality too. For More Information You Can Refer To :
- Q: Can solar panels be installed on a boat or RV?
- Yes, solar panels can be installed on both boats and RVs. They are a popular and efficient way to generate electricity while on the move. Solar panels can provide a reliable source of power for charging batteries, running appliances, and lighting, making them a great option for sustainable energy on the go.
- Q: Do solar panels require building permits?
- Yes, in most jurisdictions, solar panels require building permits. The requirements for obtaining a building permit may vary depending on the location and the size of the solar panel installation. It is important to check with the local building department or municipality to determine the specific regulations and permits needed for installing solar panels.
- Q: What is the most powerful solar panel made?
- There are various solar farms that run turbine generators that have some rather large arrays. I suspect they'd be in the southwest but i've seen pictures of them covering a few acres. You won't find very large panels because its best to keep the panels small and just have a lot of them. This is because its much easier to have a thousand 0m^3 panels then huge 0000m^3 panel because you achieve best performance when you can align the solar panels to always face the sun. With a huge panel, you would need it to be high off the ground so it can manuver around. Small ones can all be menuvered on a small scale only a few feet off the ground so they can all be pointing towards the sun to gather the most light.
- Q: How do solar panels affect the roof's integrity?
- Solar panels can have a positive impact on a roof's integrity as they act as a protective layer, shielding the roof from various weather conditions. Additionally, solar panels can help extend the lifespan of a roof by reducing direct exposure to sunlight, preventing damage caused by UV rays. However, it is important to ensure proper installation by professionals to avoid any potential issues such as leaks or added weight that could compromise the roof's integrity.
