  1. Polycrystalline Solar Panels (Poly-SI)

This type of solar panel is made by melting raw silicon which may be a quicker and more economical process than the one used in making monocrystalline panels. It makes them the cheaper choice. They have a blue speckled look and their angles are not cut. They have lower efficiency and a lower life span compared to monocrystalline solar panels. 

2nd Generation Solar Panels

They are called the &#;thin-film&#; types and are typically used for photovoltaic power stations in buildings or compact solar systems:

  1. Thin-Film Solar Cells (TFSC)

They are made by placing one or more photovoltaic material films like silicon, copper, or cadmium onto a substrate. These solar panels are the easiest to produce and since there is less material needed for their production, they are relatively cheaper too. They are flexible and less affected by high temperatures. However, they are granted the shortest warranties because of their short life span compared to mono- and polycrystalline solar panels. 

  1. Amorphous Silicon Solar Cell (A-Si)

This type of solar panel uses triple layered technology and is considered the best in the thin film variety. They are frequently used in solar-powered pocket calculators. By &#;thin&#; it means these films are about a thickness of 1 micrometer (one-millionth of a meter). These solar cells are less effective than crystalline silicon types but they are comparatively cheaper.

3rd Generation Solar Panels

This group refers to a variety of thin-film technologies which are mostly still in the development or research phase:

  1. Biohybrid Solar Cell

Still in the research phase, biohybrid solar cells are discovered by a team from Vanderbilt University. A lot of the materials used in producing this cell are the same as traditional solar cells but a combination of multiple layers is done so the conversion from chemical to electrical energy is made more effective. More details of how biohybrid solar cell works are recorded in the American Journal of Optics and Photonics.

  1. Cadmium Telluride Solar Cell (CdTe)

This solar cell is made of cadmium telluride which produces cheaper merchandise with a shorter payback time. The technique used in making these solar cells needs the least amount of water for production. CdTe solar cells allow you to keep your carbon footprint as low as possible. However, the product can be toxic once inhaled or ingested.

  1. Concentrated PV Cell (CVP and HCVP)

These cells produce electrical energy the way typical photovoltaic systems do. They have an efficiency rate of up to 41% and are the highest out of all photovoltaic systems so far. They have curved mirror surfaces, lenses, and cooling systems that help increase their efficiency rate. 

Considerations for Choosing the Best Solar Panels

There are many things to consider when choosing the best solar panels to use for your home, RV, or marine vehicles. Here are some of the most important ones:

There are three main categories of solar inverters:

  1. On-grid inverter

This converts DC to AC and then sends excess energy back to the grid. They are also connected to the utility grid.

  1. Off-grid Inverter

This converts DC to AC from a battery. They can power up residential and commercial projects.

  1. Hybrid Inverter

This also converts DC to AC but it can be used with both an on-grid system and an off-grid system.

Solar Panel Mounting Options

Solar panels need mounts which are racks or frames that can keep them in place. Solar mounts are designed to be flexible so they may be properly positioned in most sections of your property or vehicle. Here are some mounting options to choose from:

  1. Ballasted Mount

Ballasted mounts sit on top of the ground and are held down by the solar panels&#; weight. They are usually the popular choice because drilling is not required to install them. This is typically used in low-slope and roof-mounted solar projects.

  1. Mechanically-Attached Mount

Other solar projects are best mounted using mechanical attachments. For example, roofing systems that have a thick layer of insulation between the roof deck and the roof membrane would benefit more from mechanically-attached mounts. Varying mechanical attachment methods are used to accommodate different roofing systems.

  1. Fixed Mount

Fixed solar panel mounts may be free-standing or attached to the roof. You may even build your own stand! They are relatively cheaper than the other types of mounts. Just make sure to choose the best orientation angle that will enable the solar panels to get maximum solar energy output.

Tax Rebate on Solar Panel Systems

Did you know that you can get tax rebates for owning a solar energy system? Yes, the one-time federal residential solar energy credit allows you to get a portion of the cost of purchasing and installing a solar energy system on your federal tax return. If you installed a solar panel system before December 31, , you can get a 30% tax rebate. The rebate goes down to 26% for solar panel systems placed between and . Rebate falls further down to 22% for systems installed in and may eventually expire in unless Congress renews the program. 

To claim the rebate, you must prove that you own, and not just leased, a solar photovoltaic system and that it is located in your primary or secondary residence. In case you financed the system through the supplier and are obligated to pay in full as stated in your contract, you may claim a rebate based on the full amount of the system. As per the Department of Energy&#;s Office of Energy Efficiency and Renewable Energy, the costs covered are prices of panels or photovoltaic cells, assembly and installation labor costs, inspection and permit fees, and sales tax on some expenses.

To claim the rebate, you need to complete and attach IRS Form to your federal tax return (Form or Form NR). It&#;s also good to note that many states offer varying rebates and tax credits aside from the federal ITC.

Take your time and don&#;t rush!

When choosing solar panels to use for your home, RV, or marine vehicle, the best approach is to take your time, consider all the options available at your disposal, and decide based on your basic and immediate needs.
