The key thing is blast as many watts at the solar cells as you can. The colour you want varies with the type of solar cell, with maximum sensitivity ranging from infrared to ultraviolet. Many solar cells are most sensitive to blue light. Would it not be easier to hotwire the lights for an external charger? I know it's not what you asked, but it's what I would do.

1. Any solar lights give off yellow light?

Hi. Yes. Many have a yellow LED. We have a dozen in our yard purchased from Walmart

2. Do solar lights for the outside home really work and do they last?

Solar lights work fine. Mine, from Walmart, are 3 years old and still going. BUT solar is not for you. They do not give off anywhere near enough lighting for your purpose. They are decoration only. You need wired lighting.

3. How long do solar lights stay on?

It depends on the type of lights you have. Accent lights will stay on all night with a few hours of sun, and often into the next cloudy/rainy night if the battery has stored sun. Lamps and Lamp posts are the same thing. You want to make sure you get good ones though, and look for ones with Lithium-Ion batteries. There are also decorative lights that stay on, such as lanterns or floating lights for pools. And floodlights/security spot lights that can stay on up to 2 minutes every time the go on for up to 100 times a night, or for up to 8-10 hours continuously.

4. 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.
