The 30% solar energy tax credits available to homeowners and businesses to install solar energy systems was recently expanded and extended.
A dollar-amount cap was removed from the credit for residential solar water heating systems, and the availability of the credit for all systems was extended through the end of 2016.
Many state and local governments also offer incentives.
The cost of solar components has been dropping, and electricity prices will likely go up.
Taken together, these developments make installing a PV system quite appealing.
Here is a list of just some of the many incentives available, both federally and locally:
Solar energy systems turn the power of the sun into usable electricity for your home or business.
Solar power systems can be large or small.
Rather it’s a system designed to power a single device, or an entire solar home power system, the choice is yours to make.
They are very efficient, and with the increasing investment and ingenuity of manufacturers, the upfront costs are dropping.
There are even options like the feed- in tariff that offers discounted or free solar panels.
Solar Energy Systems Components
• Solar panels are made of solar cells that convert the sun’s rays into usable electricity
• A power converter, also called a inverter
• Racking system for the solar panels (such as for your roof or a ground mount)
• Electrical interconnections
• Other mounting gear
• Maximum power point tracker (MPPT)
• Battery system and charger
• Solar tracker
• Energy management software
• Solar concentrators/ ground equipment
Different Kinds of Solar Power Systems
As stated above, these solar power systems can be very large, or very small.
It really just depends on the context of your situation and power needs.
Rather you want to make yourself completely independent with a off grid system, also called a stand alone system.
Or, you can go with the most popular and economical option, and tie your PV system into the local electric grid, allowing you to sell your surplus energy, and allowing you to avoid having to use a battery back up system.
Lets take a look at some of the main types of PV systems that are used:
Stand Alone Solar Energy Systems
• A standalone (also called an off grid system) is not connected to the main electrical grid
• Can be large or small
• Often a battery storage system is used
• In non-portable applications a lead acid battery is normally used
• A charge controller is used to avoid over charging the battery
• The charge controller is also used to increase the efficiency
• Power converters are also used (inverter)
• Standalone solar systems are used by NASA to operate satellites and space vehicles
• Most do it yourself (DIY) solar kits are standalone systems
Grid-connected Solar Energy Systems
• Grid connected solar power systems are connected to the public electricity grid
• Feeds energy directly into the grid
• Uses a special grid tie converter
• Reduces your power bill
• You make money by selling any surplus energy to the electric company
• Easy to install
• No batteries Needed
• No power storage loss
• Offsets the use of fossil fuels
Solar Power Systems
are Eco friendly
If you are like me, and care a great deal about our eco system, then a PV system is right up your alley.
By utilizing solar energy as an alternative energy source you will be reducing the world’s dependence on crude oil and coal, among others.
Here is an overview of how solar energy systems help you live a sustainable life:
• Solar energy reduces your carbon footprint
• Solar energy lowers the human impact on global warming
• PV systems lower the pollution in the air, hence increasing your life expectancy
• Solar power is an alternative energy that does not produce acid rain or smog
• Solar power decreases harmful greenhouse emissions
