Differentiating On and Off Grid Solar Power Systems

The solar energy has created revolutionary changes in the world. It has given a new hope of getting energy without harming nature. Since the solar power has introduced, it has been updated to make it a valuable object that could become an integral part of our lives. Countries like UK, USA, China and India have realized the power of solar and have planned to move to the energy to a large way. Year after year, modification has been seen in the utilities used for solar power. Here you come to know about on and off grid solar systems to choose a suitable one for yourself.

Off Grid
An off-grid is the utility that can make you independent in terms of getting power. Though, the initial investment on off-grid is more than on grid, the result you get is remarkable. Off-grid has several features. It has solar panels and batteries to store electricity to offer you with 24 hours electric supply. Batteries play an important role and distinguish off-grid to on grid. When the solar panels don't generate enough electricity to sustain your household or commercial functions, for example, at night, batteries supply electricity. Thus it offers round the clock power supply.

On Grid
The system has no batteries. It has PV panels, one or several inverter, grid connected equipment and a power conditioning unit. Unlike stand-alone solar system (off grid), a grid connected system is affordable. It is because there are no batteries. When it is a sunny day, the on-grid PV system works smoothly, providing more power than consumption. It offers net metering benefits. It is the net energy between import of grid energy and export of generated energy for a billing month. The system fully utilizes the solar in first priority and the remaining power is taken from the grid. Government of many countries offer subsidies up to 70% for on-grid. The power consumption from the generator is lower with grid connected solar systems.

While you are on the way to plant solar panels, it is must to consider the difference between off grid and grid connected solar power system. Take help from a reliable source like a solar plant company. Clear your doubts. It is a big investment that seems profitable in the upcoming future. Go ahead for to equip your office or home with solar energy. This is a revolutionary way to generate electricity.

How to Shop for Solar Street lights

Solar street lights have changed the look of villages in India. After 60 years of independence, many villages of the country were deprived from the facility of electricity. Now they are lightening up and the credit goes to solar lightening systems. The PV street lights have come up as a smart alternative of electric street lights. They are wireless, need less maintenance and durable. The article focuses on some important steps to buy solar street lights.

 Estimate the Number of Lights
 Measure the area where the street lights are planning to setup. Now decide the distance each light should maintain. This is the way to count the number of street lights you need. If this step is avoided, you may end with ordering more lightening system or order a few. With accurate estimate you can order the light system in bulk. It may give you some discounts.

Evaluate the Solar Panels
  It is important to evaluate solar panels carefully. There are two types of solar panels- poly-crystalline and mono-crystalline. Conversion rate of mono-crystalline is higher than poly-crystalline. The solar panels are also varied from wattage. Carefully choose the panel that can provide enough electricity. If you have confusion, get guidance from experts.

 Decide the Battery
 Each solar street light has a battery that stores the energy to use during night in form of light. The lifecycle of a battery is very important. It will affect the backup power. Carefully choose the battery. There are usually two types of batteries- Lead Acid Battery and Gel Cell Deep Cycle Battery.

 Pole Quality
 Strong poles are necessary because solar street lights can destroy due to wind and storm. Consider the pole with wind resistance quality.

 Lightening Fixtures and Controller
 These components of street lights cannot be avoided. Make sure the street light has LED light fixture as it has higher lumen with lower energy consumption. It can lighten up the road whole night. Controller is a necessary component that controls switch on and off feature. The sensor of controller allows street lights to automatically on and off by sensing day and night. It also controls overcharging of battery, dimming and lighting.

 Shopping from a Recognized Brand
Always consider solar street light manufacturers in Kolkata or any part of India that have good reputation and are registered company. You can prevent yourself from purchasing poor quality street lights.

Top Solar Items that You Cannot Ignore

Solar technology has created a new revolution in the world. It has given a hope of 24 hours electricity without causing any harm to nature.  The power solar has been recognized by the world. Multiple items have invented that work under solar power. There are lots more to invent. Below are top items that work with solar energy.

Solar Torch Systems
This could be the first thing that uses solar energy to charge and work as a wonderful companion during dark nights. The torch has been invented for the use of  Defence Force, Forest Departments and villagers. Now, it is used by a large number of civilians. These solar torch items are not as heavy as the normal battery torch products.  It has a LED light, in-built battery charger and the solar equipment to charge the battery. Long backup support is provided. It is a time investment because you are not going to pay to charge batteries.

Garden Light
In order to save money, many of you would like to switch off the garden lights. Now, you don’t need to think about it because an alternative is available in form of solar garden lights. Like solar street lights, solar garden lights have a mounted PV panel that charges and stores energy for night. Some solar garden lights have sensor that keeps you away from the responsibility of on and off lights. They automatically switch on and off.  Your garden will be full of light all through the night. It enhances the look of your premises and at the same time keeps your home away from strangers.

 Swimming Pool Lightening Systems
Your home garden with swimming pool reveals the standard of living. Swimming pools look beautiful in the daytime as well as night. To beautify the pool at night, all you need to setup good lighting systems. Solar swimming pool lightening systems are a smart alternative of electricity lights. Rainbow colour lighting fixtures are available that enhances your swimming pool appearance as well as the garden. Decide the type of lighting fixture you want for your swimming pool and make shopping according to it.

Solar Water Heaters
It is a great invention. These water heaters are available primarily in two ranges- industrial and home. Choose a suitable range.

Planning to Setup
According to your requirements you can setup solar panels on the rooftop of your home. Make sure you have adequate space in the rooftop to setup solar panels and the rooftop gets adequate sun rays (minimum 7 hours) in a day. The electricity supply of about 5000 watts could be enough for a house per day. It means you need to install at least 20 panels of 250 watts. This number is sufficient to run a few lights, a water pump and a refrigerator. It will minimize your dependency on power grid electricity. More panels produce more power. You may able to sell electricity. 

The decision of battery installation is based on whether you want to entirely depended on solar for electricity or want to use grid electricity along with solar. If you want to use solar energy as a backup power there is no need to buy batteries. In case you want supply of electricity from solar at night, battery installation is must.
A power inverter is an integral equipment of solar system. You can connect the solar panels directly to a power inverter and then power grid. If you are using a battery, connect the inverter to the battery first and then the power grid. Solar panels produce DC power (direct current) whereas your home power uses AC (alternating current). The Inverter changes DC to AC. 

Other necessary equipment required for solar power supply are an electricity shunt and a circuit breaker. They break the current to supply adequate amount of electricity to your house and prevent damages of electricity appliances.
