Our complete solar kits contain high quality, listed components. Every electrical component needed for a successful project is included in the package. All components have been carefully chosen to work efficiently and enhance the system's performance.
Photovoltaic (PV) Panels, also known as Solar Modules convert sunlight into electricity. A solar PV module is made of a group of cells connected together. The majority of commercial photovoltaic cells are made of super pure Silicon (Si). Depending on the way the silicon is treated during production, solar Si modules are categorized in: monocrystalline, polycrystalline and amorphous panels. Amorphous modules are also known as Thin Film. Monocrystalline silicon modules hold the highest light-to-electricity conversion efficiency.
Grid-tie, or utility intertie, inverters convert DC power from solar PV modules into AC power compatible with the utility grid. The AC power output can be utilized in the home or building; the excess power will be fed to the utility grid. Solar grid-tie systems require the use of a bidirectional electric meter which will allow you to know how many kWh were supplied to the grid. In most cases the utility company will credit the system owner for the green energy produced by the solar system.
The inverter is the heart of every medium to large size solar PV system. An inverter is an electronic device that converts direct current DC power from batteries or solar modules into alternating current AC power to operate lights, appliances or anything else that normally operates on electricity supplies by the utility grid. Off-grid, also known as Standalone, inverters convert the energy stored in batteries into usable power equivalent to the power available in a home outlet. Inverters come in many varieties and sizes, with different qualities and features that optimize them for particular applications.
Whether you are using solar, wind or conventional power to charge your batteries, in this section you will find all the parts and components you will need to have a safe and long lasting battery system
The function of a charge controller is to regulate the charge and discharge of single batteries or battery banks. Besides this main function charge controllers often offer other features like, metering and data logging, low battery disconnect, built-in lights control to turn lights on and off during the night. Charge controllers can be found in sizes ranging from 4 to 80 amperes and nominal voltages of 12, 24 and 48 volts. The simplest and more inexpensive charge controllers stop the charge of the batteries when they are full and will resume charging when the batteries reach below a preset voltage. Pulse Width Modulated (PWM) charge controllers turn on and off very rapidly; holding the batteries fully charged and making better use of available power. Maximum Power Point Tracking (MPPT) charge controllers would find the point in which the source can deliver power most efficiently, and then charge the batteries. MPPT charge controllers are normally used in larger arrays; they also allow the use of modules with higher rated voltage. MPPT cost more than other charge controllers but can deliver up to 30% more charging capacity from the solar panels to the battery bank.
PV modules require special connectors for connections between the modules and other devices. In this section we display the connectors that are widely used by PV module manufacturers. We also Include a selection of heavy duty cables for battery interconnection.We recently added PV Cable or PV Wire to our catalog. PV Cable will be required in certain type of applications, especially in larger PV systems.
Solar systems consist of more than solar panels, batteries and inverters. Surge protection, safety disconnects and grounding are all an important part of the system. There is an endless list of parts and components you can incorporate into your renewable energy system; please contact us if you can't find what you are looking for.
In this section we show the tools that you might need to install, wire and service your solar PV system. We also offer devices that will help you evaluate the solar resource available for your site.
Wind powered battery charging systems are cost effective in locations where the average wind speed is 9mph or more. In places where the wind resource is inconsistent, it can be combined with solar photovoltaic modules for a reliable power source. Most wind generators are designed to deliver maximum power at wind speeds of 30mph. Wind turbines need to be mounted at least 20 feet above the ground in a location free of obstructions.
Solar water pumps operate anywhere that the sun shines and the longer it shines the more water gets pumped. In order to get the maximum benefit from the day light, direct current (DC) water pumps have a much slower water flow than conventional AC pumps. DC solar pumps he pumps are designed to efficiently operate for as long as the sun shines. Some DC pumps can operate directly from the solar PV modules, eliminating the use of batteries.
Webo Solar offers all-in-one racking and water proof flashing designed to securely mount PV panels and complete solar photovoltaic systems to boats, RVs, homes and buildings.
When using solar energy for lighting systems it is always recommended to utilize fixtures and bulbs which operate directly from DC current; this is in order to minimize energy losses, simplify the systems and reduce cost.
Our direct current (DC) refrigerators and freezers are the most energy-efficient models available. They keep food fresher longer by maintaining high humidity, which prevents freezer burn and wilting caused by water loss in food. All of them operate a low voltages of 12 and 24 volts DC.
More Electric Vehicles (EV) are seen in American highways and cities. These electric vehicles are normally charged at home or offices equipped with EV charging stations. There are 3 types of chargers that can be used for charging EVs. Level 1 chargers are usually stored inside the electric vehicles and can be used with any 120 VAC outlet. Most of the chargers that you will find in this page are Level 2 chargers and are those meant to be used in homes or businesses. Level 3 chargers are for commercial use and need a different level of infrastructure to be installed.
