What To Look For In Solar Panels

Can A House Run On Solar Power Alone

Flexible Solar Panels – What To Look For

Practically, it is not often possible. This is because solar only works when the sun is shining – which means when it is cloudy or nighttime, they do not generate electricity. There are some battery solutions to provide power during these times, but they still tend to be quite expensive. Most homes with solar panels still rely on the grid from time to time.

What To Look At When Selecting The Best Solar Panels For Your Project

1. Panel Type: Monocrystalline vs Polycrystalline

There are two main types of solar panels: monocrystalline and polycrystalline. Which one you choose will impact the overall look of your system, its cost, how much electricity it will produce, and how much space your system will cover.

Monocrystalline panels have an overall darker tint to the cells and are typically the more efficient option. Panels with a higher efficiency mean you can produce more electricity with fewer panels, so your overall system takes up less space. But for all their advantages, monocrystalline panels are often the more expensive option.

Polycrystalline panels have a bluer tint and are typically less efficient than monocrystalline, meaning youd need a few more panels to generate the same amount of electricity. However, they do often come at a lower price, and despite the additional panels youll need, will likely be the cheaper option.

2. Panel Color: The Backsheet and Frame

Another way you can control the look and price of your solar system is through the selection of backsheet and frame color.

Each panel is composed of several silicon cells that are placed on a backsheet. This backsheet shows through the gaps between the cells and creates a grid-type design. Some manufacturers offer solar panels with black backsheets instead of the typical white.

How To Buy Solar Panels And What To Look Out For

When scouting for a solar panel company in Massachusetts, you must know what to look for. The quality and installation of the solar panels will dictate how long they will last and how well they will perform. If youre planning to get solar panels, you must consider the following aspects:

Panel type. Solar panels can either be solar thermal or photovoltaic . Both absorb raw energy from the sun, but PV is the one that produces electricity. Solar thermal is used for heating and other active systems in your home.

Footprint. Another important consideration when buying solar panels in Massachusetts is the carbon footprint. Ask the provider how efficient the solar panels are and how much electricity they can produce. Make sure that the footprint and capacity of the solar panels suit your needs.

Maintenance needs. While most systems will require regular solar panel repair and maintenance, you should consider how often yours need to be serviced. The durability of the panels is critical to ensure that you will have a low operating cost for our new solar panel system.

Warranty. A solar repair company in Massachusetts would usually offer at least 25 years of warranty for their panels. Here at Beacon Solar, we give you the best guarantees on every panel we install.

There’s More Than One Type Of Solar Panel

How to test used solar panels and what to look for when buying them

Not all solar panels are the same. First, you’ll want to consider your choice between otherwise known as solar electric and solar thermal panels. Photovoltaics are far more common, and use solar cells to directly convert sunlight into electricity. Solar thermal panels, on the other hand, uses mirrors to concentrate sunlight and is typically used for water heating. Solar thermal is more efficient but only is maximized when the sun is out. PV panels are more versatile and longer-lasting.

In addition to the type of solar panel that you want, you’ll also have to take into consideration the same things that you would for any major purchase: things like performance, durability, and warranty. These will all vary, and some panels will be better suited for your particular needs. Make sure to do your research and seek out reliable sources and other user experiences to get the best information before making your decision.

How Do Solar Panels Work

Solar panels generate electricity from solar energy. The panels can produce electricity even on cloudy days, because they do not need direct sunlight. They use the light energy from the sun, not the heat energy.

A solar panel inverter, which is part of the solar system, converts the direct current to alternative current, so it can be used at home. The generated electricity is then used to meet your needs. If you produce more electricity than you use, it is exported back to the grid. During the night or in occasions when you use more energy than you generate, the electricity is provided by the grid.

What Do All Those Numbers Mean

The learning curve for solar panel info can be pretty steep.

Some of the most baffling moments can come when trying to decipher solar panel statistics.

Solar panels are rated in a dizzying variety of categories and it can seem like an uphill battle to understand what the numbers actually mean.

So let’s keep this as simple as possible.

The following are some of the main specs you should be looking for when researching solar panel info.

I’ve provided an explanation of each category and what it means to you.

So let’s see if we can make sense of these solar panel numbers!

  • Rated Power at STC This measures the power output of a panel when it is receiving 1000 watts per square meter of solar irradiance at 25°C.

This is our starting point because this value will be equal to the “advertised” power of the panel. In other words, if you buy a 180 watt solar panel, its rated power at STC will be 180 watts. Simple, right?

  • Rated Power Tolerance This spec tells you the range within which a panel will overperform or underperform. In other words, a panel may say its 180 watts but if its rated power tolerance is +/-5, you could get anything from 189 watts to 171 watts in ideal conditions.
  • What should you be looking for? For maximum power output, look for panels with a small negative number or only a positive number.

  • Rated Power Per Sq. Ft. This is a measure of “power density”. The higher the power density the less space you will need to produce a certain amount of power.

    Tracked Mounting Vs Fixed Mounting For Solar Panels

    You will need to think not only about the type of solar panel that best suits you, but also how you want it mounted. Most likely, you will want to go with a flat mountmost homeowners do because they have pitched roofs. But if you have a flat roof or if your panels will be installed in your yard rather than your roof, you may choose to mount them on trackers.

    Whats the advantage of trackers? They move your solar panels so that they can follow the sun, usually via a motorized mechanism. This makes the panels significantly more efficientas much as 25% to 35%especially if a roof is shaded during part of the day.

    But again, with increased efficiency comes increased cost. Trackers can add several thousands of dollars to the cost of a residential solar panel installation.

    What Factors Affect The Number Of Panels Youll Need

    Solar Panels Maine

    The question of how many panels you will need will be determined by your installer depending on a number of factors:

    8. What percentage of your electric bill do you hope to offset with solar energy?

    9. How much electricity do you use in an average month?

    10. How much sun does your area receive?

    The National Renewable Energy Laboratory provides a handy map that tells how many kWh you can generate in one year from 1 kW of solar panels if they are situated in an ideal spot in your area. Find their maps here: . Your installer will adjust for expected losses from heat, wiring, etc.

    11. Does your state/utility offer Net Metering ?

    12. Will your installation include battery storage?

    13. What is the maximum power output and efficiency of the solar panels you will install?

    14. How many panels you need will depend largely on two main factors: power and production.

    What Can 100 Watt Solar Panel Power In My Vehicle

    How much energy will a 100-watt solar panel produce? It depends on how many hours of sunlight the solar panel receives. If the following occurs:

    • Four hours of direct sunlight means a 100-watt solar panel will produce 400 watts of energy per day.
    • Five hours of direct sunlight means a 100-watt solar panel will produce 500 watts of energy per day.
    • If you have three 100-watt solar panels that each receive four hours of direct sunlight, you will generate 400×3 or 1,200 watts of energy per day.

    This highly rated TopSolar portable kit with USB connections will be suitable for those looking for a lower-powered system Advertisementstake a look here.

    If you are trying to figure out how many 100 watt solar panels you need to power your outdoor living lifestyle, you will need to add up the energy usage of all the gear you bring with you.

    Keep in mind that the energy a solar panel produces depends on how long it is in the sun and the quality of the sunlight.

    If you are a DIY explorer, you may find the above list a perfect challenge. However, for those of you who are no DIY personalities, there are kits available too.

    What Equipment Will Be Installed And Where Will It Be Installed

    Many solar companies want you to sign on the dotted line before they even show you a system design. Make sure you are dealing with reality before signing a contract that may have cancellation penalties. The salesperson may be overstating the productive capacity of your roof, so make sure they show you a design of where the panels will be installed, what type of inverter system they will be using, and the brand of the different components. Not all solar is created equal. You want to make sure your installer uses a high quality, high efficiency panel that will maximize your roof space and generate the most power over the life of the system. I recommend SunPower panels because they are the most efficient panel available for a residential application, they perform better than any other brand over time, and with SunPowers new integrated micro-inverter technology will be the cleanest installation on your home. Since SunPower panels are more efficient you can offset more of your electric bill and maybe even leave some room for future expansion if you have an electric car in your future.

    The Solar Rebate: Still Very Much Alive And Kicking And Generous

    The famous Australian federal solar rebate, technically known as the STC scheme, acts as a point of sale discount off a solar installations final cost.

    All the prices you see advertised will already include this discount. Its worth about $500 per kilowatt of solar panels installed, but this will vary slightly depending on where you live.

    So, for example, 6.6 kW of panels attracts around $3,300 in rebates.

    Anyone can claim the rebate, even if youve already bought solar power systems in the past and want to buy a new system.

    The only restrictions on claiming the rebate are:

    • Your system installation must be less than 100 kW in size .
    • You get it installed and designed by a Clean Energy Council accredited professional
    • You use panels and solar inverters approved for installation in Australia by the Clean Energy Council .

    The federal solar rebate is slowly being phased out. It reduces by one-ninth of todays value every January until it goes to zero in 2031.

    Approximate solar rebate for 6.6kW of panels .

    For Victorians, the Labor government introduced a state-level rebate that offers eligible recipients an extra $1,400 off the cost of a solar system installation at the time of writing.

    Pro-tip: The federal rebate is based on solar panel capacity, not the inverters size. This often makes adding panels over and above the inverter rating very worthwhile.
