SOLAR PANELS

Solar panels convert visible sunlight to renewable electrical energy. Often confused with solar collectors used for heating water or others used for heating air, solar panels are sometimes also referred to as photovoltaic modules (PV) or solar modules. Solar Power Mart and our knowledgeable staff focuses on making it easier for you the Do-It-Yourself to design and decide upon the solar panel system for any project, whether it's simple solar science experiment, solar camping gear, a mobile solar panel on an RV solar power system or a full residential solar power system.

Solar panels (a.k.a. Photovoltaic or PV modules) vary in length and width, and are often about 5cm thick. They are generally about 2kg or less, but the larger ones can be cumbersome to carry on the roof. We carry a wide selection of solar panels: framed, foldable, roll able and laminates for the roof. Framed solar panels are the industry standard, most cost effective, and applicable for most home solar panels applications.

Flexible / Roll able Solar Panels are lightweight. Many people use these roll able panels on boats because they are durable and can be easily stowed after use.

The number of solar panels you will need depends primarily upon the amount of electricity you are trying to produce and the insulation in your area. Insulation can be thought of as the number of hours in the day that the solar panel will produce its rated output. This is not equivalent to the number of daylight hours.

You'll find solar panels in a variety of wattages. Watts are the main measure of a solar panel, along with nominal voltage . For a rough idea of how many watts of solar you will need, start by dividing your electrical usage (in watt-hours per day) by the insulation in your area. Bump that number up by 30-50% (to cover system inefficiencies) and you'll have an idea of the number of watts of solar panels you will need.

If you could still use a little help with the math, please give us a call and tell us how much electricity you are trying to produce (in kwh/month or watt-hours/day) and your location, and we'll help get you started.

What types of solar panels

Most solar panels can be classified as monocrystalline, polycrystalline or amorphous. This is based on the silicon structure that comprises the cell. It's not quite as complicated as it sounds. Basically a 100 watt monocrystalline solar panel should have the same output as a 100 watt polycrystalline panel and a 100 watt amorphous panel. The main difference is the amount of space which the panel occupies. Because the monocrystalline structure is more efficient than amorphous in turning sunlight into electricity, the amorphous panel of the same wattage will be physically larger. By the way, when talking about efficiency of solar panels, keep in mind that solar panel efficiency is still only about 13-18% efficient in turning sunlight into electricity. Often amorphous panels are less expensive than the crystalline panels. If space is not an issue, than an amorphous panel could be a great option. Additionally, amorphous panels perform better than crystalline panels in very hot temperatures and are also slightly more tolerant of partial shading.

Locating your solar panels - very important!

A key factor in the effective use of solar electricity is proper placement of the solar panels. Make sure to locate the panels where they will receive full sunlight between the hours of 10 am and 3 pm. Be sure that the solar panels will not be shaded by shadows from tree branches, chimneys, other structures, etc. Once again - NO SHADE! You will be mounting the solar panels on the roof, the ground or a pole.

How long will solar panels last?

Solar electric panels use the sun's light to generate electricity. They generate electricity during sunny daylight hours and can be used in a system with batteries so that the electricity can be used at other times as well. Also known as Photovoltaic (PV) modules, solar panels are the main component of a solar electric system. (And the main expense!) Along with an inverter, mounting system, batteries and Solar Charge Controller, solar panels can produce electricity to power the energy efficient appliances and lights and appliances in most households. Solar panels themselves generally last over 25 years, and require little maintenance. Many of the first solar panels produced in the 50s are still in use today. Many of the solar panels have a 20 year warranty or more. A common warranty states that the panels will produce at least 80% of their rated power after 20 years.

What else will I need with a solar panel?

In addition to the solar panel mounting kit hardware, there are additional components that you will need for a safe installation. If you plan on using just one solar panel in a battery based system, you will need a solar charge controller, and over current protection to protect each major component of your system: solar panels, solar charge controller, batteries, and inverter. If you plan on using more solar panels in your system, you will also need to safely wire the photovoltaic solar panels together and to the charge controller. An easy and safe way to do this is by using MC (multi contact) connectors found in the wiring for solar panel section. This connector connects to the cables coming from the solar panel and can be cut in half to expose bare wire. Combiner box are used to collect the bare ends of the wire from multiple solar panels, and then from the combiner box you can run just one set of wires to the solar charge controller. For each series string of solar panels, you will need an appropriate sized breaker.

SOLAR BATTERIES

Solar batteries are really deep cycle batteries that provide energy storage for solar, wind and other renewable energy systems. Different from a car battery, a solar battery is capable of surviving prolonged, repeated and deep discharges which are typical in renewable energy systems that are "off grid" (disconnected from the electric utility company).

Solar Batteries (Deep Cycle Batteries) are a key component in a stand-alone renewable energy system. If you are installing a solar panel system that will be tied to your utility grid, you will still need deep cycle batteries if you are trying to use power in the event of an outage. Without deep cycle batteries, you can only use power at the time you produce it. (i.e. You will not have power when the sun isn't out if you don't have batteries in your solar electric system.) In renewable energy systems, Deep Cycle Batteries provide the energy storage for your system. Unlike your car battery, deep cycle batteries that are used in renewable energy applications are meant to be discharged and recharged (cycled) repeatedly. To maintain healthy batteries and prolong battery life, most manufacturers suggest limiting the depth of discharge to about 20%. (That means the deep cycle batteries will be at 80% capacity or better.) At the very least, do not allow the batteries to be discharged below 50% Depth of Discharge (DOD). Often an inverter will have a Low Voltage Disconnect feature that will disconnect loads at a given set point. Low voltage alarms can provide audible warnings as well. Ammeters, Voltmeters, Battery Monitors can help better maintain deep cycle battery health and provide statistics about the overall health of the system.

Types of Solar Batteries

When selecting solar batteries (deep cycle), you'll have the option to use flooded lead acid (FLA) batteries or sealed batteries (AGM or Gel cell). Keep in mind that FLA batteries require a bit of maintenance, however, they generally last longer than their sealed counterparts. Water Miser Vent cap - Reduces Battery Watering can reduce the frequency that the deep cycle batteries need watering. You'll need one vent cap for each 2 V cell. Desolater are another good low cost investment that can help prevent sulfation and boost the performance of the batteries. Flooded Lead Acid batteries can build up sulphate crystals on their lead plates over time.

Sealed deep cycle batteries may be a bit heavier and therefore cost a bit more to ship. Deep cycle batteries come in many sizes: from sealed batteries that are less than 10 pounds to flooded lead acid batteries that weigh over 200 pounds each! They can be small (and fit in a backpack) or large (2'x 2'x 1') and anywhere in between. Generally the size and weight correspond with amp hours of storage. So if you need a lot of electrical storage, be sure that you have the appropriate space to house the batteries.

Whether you have one battery or a bank of 36, proper storage is essential. Enclosures can provide a neat and safe way to contain the batteries or you can build your own battery box. Often people add an optional battery Ventilation fans that can vent the hydrogen gas that is naturally exhausting by the lead acid batteries. The vent also helps maintain a comfortable operating temperature for the batteries in cold climates.

Deep Cycle Batteries Storage Capacity: Battery Bank Sizing

Deep cycle battery banks consist of one or more batteries, and are measured in amp hours of storage capacity. Each battery can be 2, 4, 6, or 12 volts. The choice of individual solar battery voltage will depend upon your total system voltage (12, 24 or 48 vdc) and your desired amp hours of storage. Often the 2 V batteries offer the largest amount of storage; however, you may need up to 24 of these huge deep cycle batteries, if your system is 48 volts. Connect your solar batteries (i.e. deep cycle batteries), using Battery Interconnects, in series, parallel, or a combination of both depending upon your system voltage and the storage capacity you need. Read more about this in the how to section about battery bank sizing. While batteries may be a large expense for a sizeable off grid system, with proper care and maintenance, they should last 5-10 years. Let us know how many watt hours per day you need to provide, and the number of days of storage you need, and we'll be happy to offer specific sizing recommendations for your deep cycle batteries.

INVERTERS

Inverters are used in any electric system where AC power output is needed. You are already familiar with AC power: it is the power in your house when you plug something into the wall. The inverter's job in a solar energy system is to convert the DC electricity, such as from a battery bank, to AC electricity that can be used with typical household appliances. Solar panels also produce DC electricity. Inverters are used in homes, business, RVs and boats. Off Grid Inverters are common in solar electric. Solar electric (or PV) systems can operate with or without batteries. Since each inverter needs proper disconnects on the AC and DC side, often people choose one of our self contained Solar Battery. By mounting one or two inverters on a Solar Battery, that is wired with the appropriate disconnects, you have yourself a neat and safe inverter system.

Sizing an off grid inverter (that needs batteries) is relatively straight forward. It must be large enough to handle the total amount of watts you will be using at one time. Start by listing all of the appliances, etc that you use and their wattages in our load calculator. This form will display the number of watt hours you use in a day. In order to properly size an inverter, consider which of those loads you will be using simultaneously and add up their wattages only. For example, if you will be using the 1500 watt microwave at the same time you will be running 100 watts of lighting and also running a refrigerator that will draw 500 watts of instantaneous power, you will need an inverter that can handle at least 2100 watts (1500 + 100 + 500). Once you have identified a minimum wattage, you will select an inverter that has the same nominal voltage as your battery bank (12, 24, or 48 VDC).

SOLAR CHARGE CONTROLLERS

Charge controllers come in various types. Solar charge controllers regulate the charge from a solar panel array to a battery bank. Solar lighting controllers allow you to control DC lights while simultaneously charging a battery bank from solar panels.

Since solar energy power systems almost always gather power and store it in batteries, almost every system requires a charge controller. A solar charge controller will protect your batteries from being overcharged by your solar panels and it will block any reverse current (from the batteries) as well. Solar charge controllers will actually protect every aspect of your solar power system from your batteries to your solar panels. Temperature sensors are an inexpensive addition that help the charge controller more accurately regulate the charge of the battery bank

Sizing a Solar Charge Controllers

You'll notice that solar charge controllers are specified by both amperage and voltage. You will need a charge controller that matches the voltage of your solar panel array and battery bank. (Usually 12, 24 or 48 VDC) And you'll want to make sure the solar panel charge controller has enough capacity to handle the current (in amps) from your solar panel array. The basic formula for sizing a solar panel charge controller is to take the short circuit current (Isc) of the array, and multiply it by 1.56. Be sure that the charge controller you select can handle at least that many amps. Please protect this important part of your system with appropriate over current protection before and after the controller.
