![]() Here you should not confuse with the 12V. To adequately charge your Battery you have to use a Solar Panel with equal or greater Voltage output.Īs we have selected 12V battery system, so we have to use 12V Solar panel too. Peak Solar Radiation = 1 kW/m2 ( Solar Panels are rated at an input rating of 1kW/m2.) To find out the amount of solar insolation in your area, you can use the Global Solar Atlas.Īs per the Global Solar Atlas, New Delhi, India receives 5.104 kWh/m2 per day (GTI) The term "peak sun hours" refers to the solar insolation which a particular location would receive if the sun were shining at its maximum value for a certain number of hours. The average daily sun hours (solar insolation) in units of kWh/m2 per day is sometimes referred to as "peak sun hours" too. The first step for sizing the solar panel is to identify the average peak sun hours in your area receives. Once you have finalized the Battery Size, you can turn your attention to sizing the Solar Panel for your DIY solar security camera. The battery will need to be protected in a weatherproof container, typically called a “NEMA Box.” NEMA defines standards for various grades of electrical enclosures rated to protect against environmental conditions.įor further information on batteries, please have a look at this article. On cloudy days your battery will need to supply power without help from the panel. Note: When calculating your battery size, consider how many cloudy days you may have in a row. ![]() Multiplying the Amp-Hour by 2 ensures that you are operating on the top 50% of the Battery’s cycle, giving you 50% of its capacity remains available for future use. This will help to extend the lifespan of the batteries. It is a good practice to operate the battery at 50% of its cycle. Watt-Hour required to run the whole day (24hrs) = 6W x 24 hrs = 144 Whīattery Capacity Required = 144 / 12= 12Ah So make sure the solar batteries are capable of recharging fast and store enough power for continuously monitoring & recording. The entire power required to run the Security Camera is drawn from the Battery Pack. However, these benefits come at a high cost of up to 20 times the cost of a deep cycle battery. They also have a long lifespan averaging 5 to 9 years. Whereas the Li-Ion battery can be charged fast, are lightweight compared to their storage capacity. Visit my new website: You have two good choices of battery types: Deep Cycle Lead Acid or Li-IonĪ deep cycle Lead Acid battery is less expensive and with a lifespan of 2 to 5 years and offers good performance for solar energy storage. It is is not restricted to s security camera only. Note: This article can be used for DIY Off Grid Solar System for any load. Can be installed in remote sites or geographically challenging environments. Why should you need a solar powered security camera? Because solar powered security cameras have a lot of benefits like:ģ. In this Instructable, we will cover the second alternative " DIY Solar Powered Security Camera System " Adding solar power system to the existing security camera Buy a readymade solar-powered security camera systemĢ. When we talk about the solar-powered security camera, there are two alternatives :ġ. However, it is a great idea to go for solar-powered wireless security cameras for increased and reliable security. It is never a new thing to set up a security camera for that purpose. ![]() Everyone needs security for their home, garden, and other valuables.
