The solar panel junction box is an enclosure placed at the underside of the solar PV module (solar backsheet). It is an important part through which two or more solar PV panels are interconnected. These days, the variety of PV junction boxes is manufactured in China.

The solar panel junction box is the output interface of the solar module. It wires the four solar connectors together.Each solar junction box has two wires. One wire is the DC positive (+), and the other is the DC negative (-).These can be connected to the solar PV panels either serially (series connection...

It doesn’t have to be entirely sunny for your panels to produce electricity. In bad weather, your power production won’t be 100%, but your panels will still be producing power. On a cloudy day, your panels might produce only 30% of what they normally would. The exception is a snowstorm. If it snows enough ...

Direct grid-ties systems will not produce power when the grid fails. For safety reasons, your home solar power system will automatically shut off if the power goes out. This is to protect utility workers who might be working on damaged or downed power lines during an outage from being exposed to live elect...

The solar photovoltaic panels require little maintenance. No need to wash or dust. It is, however, important to place panels where they will remain clear of shade and debris. Thus you will have to wipe them off if too much snow or leaves fall on them.Solar hot water collection arrays do not require much at...

solar panels come with approximately 3ft of Positive (+) and Negative (-) wire connected to the junction box. At the other end of each wire is an MC4 connector, designed to make wiring solar arrays much simpler and faster. The Positive (+) wire has a Female MC4 Connector and the Negative (-) wire has a Mal...

Our designer determines the optimal system size based on many factors, including each customer’s goals, the amount of electricity used, the time of day it is used, and the attributes of the solar array. The most accurate way to measure system size is in kilowatts (kW). For example, a typical 6.6 kW residen...

For a typical homeowner purchasing their solar system, it will pay for itself in just 5-7 years, resulting in a lifetime savings of well over $100,000. For someone financing or leasing their system, they can expect to save 30% right away and between $30,000 and $90,000 over the life of their system. ...

The Feed-in Tariff is a governmental program encouraging the adoption of renewable energy sources. You will receive payments from your energy supplier for the electricity you generate, even if you do not use it in your household. Payments are usually made quarterly, they are tax free and indexed to the inf...

There are three types of solar panels and they differ in efficiency and price. Monocrystalline solar panels are the most efficient. Some models can convert 25 per cent of the sunlight they receive into electricity. Polycrystalline solar panels are second in efficiency and some models can reach up to 20 per...

Solar power, like other renewable energy resources, has many environmental and health benefits. Going solar reduces greenhouse gas emissions, which contribute to climate change, and also results in fewer air pollutants like sulfur dioxide and particulate matter, which can cause health problems. ...

Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. Most homes and businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use ...

A solar panel efficiency rating gives you a measure of how much sunlight a solar panel can convert into electricity. Efficiency for different manufacturers and types of panels range from about 12% to over 20%. SunPower is recognized as making the highest efficiency solar panels in the industry, producing 4...

Your power that is produced feeds into the power grid, when excess power is produced it actually makes the meter go backwards. This off sets the price you pay for electricity against the price you are paid for putting your surplus electricity into the grid, which means lower prices for you in running your ...

Adding a solar system will definitely increase the value of your property. How much depends on which sources you go to, but we have seen in print through real estate appraisers that it can be as much as twenty dollars for every one dollar invested in solar. Although that is probably not the case for every...
