Solar Panels - Green Energy

Germany government agencies are utilizing nowadays Solar Energy to power their equipment that could not be powered in any other way than solar power. Maybe the reason is the equipment is in a remote area or for the efficiency and greener energy.

One reason that you would use Solar Power would be it is renewable energy. Clean Energy does not depend on the grid. If there is a storm, this Solar Power Camera system will still operate. Solar Energy has tax incentives. In many countries, government offers tax incentives for those who install these kinds of systems in their homes and businesses. Not only can you power your Surveillance equipment, you can also power a large amount of devices in your home and business.

Solar charge controllers, also known as solar regulators, are an integral part of any stand alone solar system. The average 12 volt solar panel produces between 12 and 21 volts, a level that would overcharge and damage a battery if transferred directly to it. Solar charge controllers work by regulating this voltage to a level that can safely charge batteries and run appliances.

There are two main types of solar charge controller, the Pulse Width Modulation regulator and the Maximum Power Point Tracking regulator. Both do the same job of regulating voltage produced by solar panels, as shown in this solar charge controller schematic:

Pulse Width Modulation Solar Regulator

Pulse Width Modulation Solar Regulators are the most common type of battery charging technology. They’re able to prolong battery life and reduce heating and sulphation while charging. PWM charge controllers are usually cheaper than their Maximum Power Point Tracking counterparts but work at around a 70% efficiency rate when transferring energy from the panels to batteries.

Maximum Power Point Tracking Solar Regulator

A more recent technological advancement, Maximum Power Point Tracking regulators offer the same battery life-prolonging properties as PWM regulators but with a higher efficiency rate of 95 to 97%. They do this by transforming excess voltage to the right level with an increase in current, rather than by simply clipping it. While they may be the slightly more expensive option, the increase in efficiency offered by MPPT charge controllers makes them well worth the money, especially if you rely heavily on solar for your power needs.

How do I work out what size of regulator I need?

To find the correct minimum size for your solar regulator, you can use the following basic installation example below, depending on whether you want to use a Pulse Width Modulation (PWM) or Maximum Power Point Tracking (MPPT) regulator. Note that assumes you are using solar panels of the same type.

How to install and determine the Solar Panel Watts

Before you install any Solar Panels make sure you are cleared legally, some communities are not comfortable with Solar Panels being installed and others require a special permit. Location must be either pointing East or West wherever it will receive the most sunlight. Besides that, you need to determine the size of the panel and wattage needed to operate this camera and the wireless access point. Solar panels are rated in Watts at 17 volts average. To determine the watts lets go ahead and multiply the total current consumption times voltage (17 Volts).
