How to Take Care of Your Battery System

by Team PVdepot.com on October 27th, 2013

Batteries support your solar system, so it’s extremely important to check on them frequently to avoid hazards. Here’s some information about possible issues you could have with your battery, and how to avoid them.

PVDepot-battery-solar-system

  • Don’t overcharge or over-discharge your battery.
    • This can cause a short cell circuit.
    • They can be caused by metals/particles that can form between positive and negative plates, faulty plates, sediment build-up, or faulty separators. All of the above are caused by overcharge or discharge of the battery.
  • Keep your battery in a temperature of 60-80 F.
    • A higher temperature will increase the capacity of the charge your battery can hold, but will eventually decrease the life of your battery.
    • Super high temperatures can cause your battery to fail and should be avoided.
  • Battery voltage should always be higher than 2.30 volts per cell.
    • If not, ‘gassing’ could occur which is a process that will eventually kill your battery.
  • Make sure the area your battery lives in is ventilated.
    • This decreases the chance of sparks and risks of an electrical fire.

The Life Expectancy of a Solar Panel

by Team PVdepot.com on August 6th, 2013

When looking into investing in solar panels for your home, you want to make sure you’re getting your money’s worth. So how long do solar panels really last? Are they worth the purchase?

solar-energy-panelsYES.

Solar panels are not only a great investment because of the lowered energy bill you will eventually be receiving, but for switching over to greener and cleaner energy.

So how long does a solar panel really last? The life of a solar panel depends on what kind of panel it is and what it was made out of. Different materials have different life-spans. Solar panels constructed from film have a really low life expectancy of only 2 – 5 years. Although, the newer solar panels made out of crystalline are extremely durable and have an outstanding life span of 20-25 years.

The warranty for the average photovoltaic solar panel is 25 years. The way engineers calculate this number is by calculating the loss of how much energy is retained by the panel each year. Their average loss had been 0.08%. So if a PV solar panels loses 0.08% of energy each year, at this rate it would take the panel 25 years to be retaining only 80% of solar energy as opposed to its 100% when it was first constructed. Once a panel drops to 80% or below of retaining solar energy, it is considered below an acceptable efficiency rate for a solar system.

But…

Most solar panels last longer than 25 years. In fact, there are some that have lasted up to 40 years! It’s very important to have your solar panels and solar system tested every few years to determine how much energy your system is retaining over the years.

Installing Solar Panels on Roofs

by Team PVdepot.com on August 6th, 2013

Solar panels are a great addition to any roof – with the exception of ones in the shade! The first thing you want to make sure of before purchasing solar panels for your roof, is the amount of sun it gets during daylight. Solar panels will provide some protection for you home and your roof, but under no means should they be installed on a roof that isn’t in good condition. If your roof is not in good shape, it must be replaced before solar panels become an addition to your home.

Workmen-install-HomeSun-s-007

When looking at how to install solar panels, the main thing to consider is the angle of the roof and how the panels will sit atop of the shingles. You must also take into account where the sun hits your roof for the longest period of time during the day, so you can get the most bang for your buck.

Depending on what kind of roof you have will determine the cost and complexity of how much installation fees will be.

Most roofs are made of shingles. This allows PV installers to attach rails that are mounted to the roof by bolts into the rafters. The solar panels are then attached onto the rails. Flat roofs are usually topped with gravel or tar so the racks have to be installed at an angle. The rails are typically cemented to the roof instead of using bolts. The rails that hold the panels usually do not require intense construction. Wooden or ceramic roofs are at the top of the price range for installation costs.

PVdepot.com offers a the best high quality section of solar panels to install on your roof, as well as the mounts and rails. Get everything you need to start your own solar system! Start supplying cleaner energy for your home with PVdepot.com.

How to Select Solar Panels for Your Home

by Team PVdepot.com on July 25th, 2013

Are you thinking about switching to cleaner, renewable energy? Ready to save some change on your energy bill but aren’t sure where to begin? Figuring out what kind of solar system and what solar panels are right for your house is the best starting point.

Measure your roof
It’s vital to determine the size of your roof in order to calculate what kind of capacity it has to hold solar panels. Also you must determine what place on your roof has the best possibility for quality array and which direction has the most sunlight. If it’s possible, measuring the slope of roof would be good information to have when picking out solar panels.

Figure out your monthly power consumption
Check your utility bills to find the average amount of energy used per month. To do so, average your monthly kilowatt-hour usage.

Pick the right solar panels!
PVDepot offers fours different types of high-end, quality solar panels at low prices.

      • solar-monocrystalline-panelsMonocrystalline, or Single Crystal, is the original PV technology invented in 1955. Monocrystalline modules are composed of cells cut from a piece of continuous crystal and are known not to wear out. The material forms a cylinder which is sliced into thin circular wafers. It has a uniform color which is dark blue.



      • solar-polycrystalline-panelsPolycrystalline cells are made from similar silicon material as monocrystalline except instead of being grown into a single crystal, they are melted and poured into a mold. This forms a square block that can be cut into square wafers with less waste of space or material than round single-crystal wafers. As the material cools, it crystallizes in an imperfect manner, forming random crystal boundaries. The efficiency of energy conversion is slightly lower.



      • thin-film-solar-cell-panelA thin film solar cell (TFSC), also called a thin film photovoltaic cell (TFPV), is a solar cell that is made by depositing one or more thin layers (thin film) of photovoltaic material on a substrate. The thickness range of such a layer is wide and varies from a few nanometers to tens of micrometers. Thin-film solar cells are usually categorized according to the photovoltaic material used. The advantage over traditional PV panels is that they are very low in weight, are not subject to wind lifting, and can be walked on (with care).



      • solar-BIPV-panelsBuilding-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or facades. They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power, although existing buildings may be retrofitted with similar technology. The advantage of integrated photovoltaics over more common non-integrated systems is that the initial cost can be offset by reducing the amount spent on building materials and labor that would normally be used to construct the part of the building that the BIPV modules replace. These advantages make BIPV one of the fastest growing segments of the photovoltaic industry.

Types of Solar Batteries

by Team PVdepot.com on July 25th, 2013

Not sure which kind of battery you need? Here are the different types of batteries that are the best quality and offered at the best price by PVDepot. Choose the right battery to support your solar system!

  • solar-sealed-lead-battery A sealed gel battery, also known as a VRLA battery, is a lead acid rechargeable battery. It’s sealed because of the liquid electrolyte that is in between two lead plate-separators. This battery vents while it charges. This battery is the lowest voltage option.
  • solar-absorbed-glass-mat A sealed AGM (absorbed glass mat) is a version of a lead acid battery and are among the safest batteries. It uses absorbed glass mats between plates. They tend to hold their charge longer than other types. It doesn’t need any maintenance, and is among the strongest of battery types as it was designed to absorb shock and vibrations.
  • solar-flooded-lead-battery Industrial flooded batteries, also known as wet cell batteries, are another variation of lead acid batteries. They are one of the most commonly-used and is the oldest type of lead-acid battery used for solar power. They typically charge slower than other types. This is not a rechargeable battery – once it dies, it has to be replaced.
  • solar-deep-cycle-battery A deep cycle battery is a lead acid battery designed to be discharged between 50% – 80% of its capacity. It’s designed for maximum energy storage and for a longer life. They are measured in Amp/Hours.

How to Pick Out a Charge Controller

by Team PVdepot.com on July 25th, 2013

How to pick the right charge controller for your solar system

solar-charge-controller-pvdepot

Solar charge controllers regulate the charge from a solar panel array to a battery bank. Solar charge controllers are determined by amperage and voltage. You will need a solar charge controller that matches the voltage of your solar panel array and battery bank. You’ll want to make sure the solar charge controller has enough capacity to handle the current from your solar panel array. PVDepot has the best prices on charge controllers.

The main function of a charge controller regulator is to protect your battery from overcharge and block a reverse current. Without a charge controller for your photovoltaic solar system you risk the life of your battery. Essentially if a solar away is not self-regulated and connected to lead acid batteries and does not have overcharge protection, your battery may short circuit or worse.

Types of solar panel charge controllers

Simple charge controllers contain a transistor that shunt (a resistor that produces low voltage proportional to the amount of current flowing through it) the Photovoltaic charging circuit, terminating the charge at a pre-set high voltage and, once a pre-set reconnect is reached, opens the shunt, allowing charging to resume.

More sophisticated controllers utilize pulse width modulation (PWM) or maximum power point tracking (MPPT) to make sure that the solar battery is being fully charged.The first 70% to 80% of battery capacity is easily replaced, but the last 20% to 30% requires more attention and therefore more complexity.
