As for the technicals, photovoltaics are only 10-14% efficient they need full sun. It's also the reason the ones with small collectors likely can not collect enough light. Also the hotter they get, the less efficient they are do you have them right next to the driveway/walkway? One last important piece of info, if just 1 cell of panel is in shade, that cell acts like a resistor that the other cells have to overcome and the efficiency drops 50%. So make sure they are in full sunlight, and no cells are blocked ever. I would start with the above first, put them in full sunlight, and angle them slightly towards the sun to try to prevent any cells from being shaded for as long as possible. Otherwise, the answer is likely you got cheap ones.
1. my goldfish always sits at the bottom of the tank.. he is alive because does move but sits for hours?
Your tank is quite small for your gold fish, however he should be a little more active. Be sure you do not have a heater and that the water temps are between 55-65. Warm water will make your gold fish lethargic. Also, gold fish require lots of dissolved oxygen. This can only enter your tank by movement of water. ie filters, waves, waterfalls powerheads etc. Try lowering your water level about 1/2 -1 inch and let the filter dump water into your tank. This will add the DO2 he needs. Also, if the water is too warm, add a few ice cubes and let them melt. This will help with him being lethargic. Once he becomes more active, gold fish love to bumb things on the surface. A plastic ball, large enough that he cannot swallow it on the surface works wonders for their attention span. I use floating orb solar lights in my outside ponds to entertain the fish. Sounds dumb, but they push them all over the pond, day and nigh.
2. Solar Lights not turning on even with new batteries, cleaned them all, and have plenty of sun.?
check all of your connections and make sure they are clean, then if that dont work, call a professional
3. Solar pergolas, gazebos & patio covers: A quick guide
When you think of solar power for the home, solar panels on the roof is what immediately comes to mind. But there are many other places you can put your panels to produce solar energy for your home. Some of the more popular alternatives available in 2021 are ground-mounted solar panels and solar carports. Another approach is to go for solar structures on the patio or in the garden, which are often referred to as 'solar pergolas' or 'solar gazebos.' Read on to learn exactly what solar pergolas and solar gazebos are and whether they make sense for you. What are solar pergolas, solar gazebos, and solar patio covers? They all refer to solar-energy producing structures built on your outdoor patio or backyard. They can be built upon existing structures on your property, or be custom-built with solar energy production in mind. You could use a small structure if you are just looking for enough energy to power outdoor lighting. But with a bigger setup, you could place enough solar panels for a 5 kW solar system or even a 10 kW solar system. A system of that size is usually enough to power your house as well as sell excess electricity back to the grid. Are solar lights and solar umbrellas different from solar pergolas, solar gazebos and solar patio covers? Yes, they are. You have probably seen solar lights and solar umbrellas, which are popular in people's backyards these days. Solar lights are smaller devices that use solar cells, which are either built-in or attached as a small accompanying unit. The cells charge an internal battery during the day and then power lights at night. There are many different types: solar path lights, solar spotlights, solar ambient lights, etc. Solar umbrellas, meanwhile, are patio umbrellas with inbuilt solar cells that power attached lights and sometimes even a USB charging station. Solar lights and solar umbrellas have limited power-producing capacity are not built-up structures like solar pergolas, gazebos and patio covers. Which is better? Rooftop solar vs. solar pergolas, gazebos and patio covers For most houses, the rooftop is the place with maximum surface area and highest exposure to the sun. It is usually also convenient to mount solar panels there, as minimal construction or modification is required. These factors are why roof-mounted solar panels have remained the most popular option for homeowners. However, in many instances, your roof might not the right place to put your panels. Here are some of them: Space constraints: Your roof does not have space for the number of solar panels your require. (Not what this figure is? Calculate the sq. ft. required for solar panels here). Shade: Obstructions like surrounding buildings or trees might block direct sunlight from hitting your roof. Unfavorable angle or positioning: You will not produce maximum power unless your roof faces south. The roof angle, or pitch, also needs to be at the right level (30 to 45 degrees) to work best. Aesthetics: Maybe you just do not like the way they would look on top of your house... Ground-mounted solar panels are one alternative to consider. But they have one big disadvantage: they require substantial amounts of real estate, space that you can not use for anything else. This is where the solar pergola, solar gazebo or solar patio cover-as well as the solar carport- enter the picture. They are all dual-use structures, so they are more space efficient than a ground-mounted setup. You might already have one of these structures out back, which you might easily be able to adapt or modify to hold solar panels. Otherwise, if you are building one of these structures from ground-up, you can go for a designed-for-purpose structure that looks looks great and is optimized for maximum solar energy production. Of course, opting for a whole new structure means adding construction costs to the cost of solar panels. Solar pergolas, gazebos, and patio covers are just one of the routes you can take to go solar. If you can not or do not want to put solar panels on your roof, you could use them in order to gain all the benefits from going solar. To see if they are right for you, find a local solar installer who can assess your property and provide recommendations.
