How Should I Go Solar?Without Getting Ripped Off:

Yes its great having a solar system installed in your home or business the benefits are huge,especially with government subsidies and rebate programs that make solar the smart choice-financially as well as environmentally.But there are also FAQs to be answer to encourage more people to go solar.Before the purchase of a solar system ask a specialist Is my home roof facing south? Are there any shade obstruction?Although solar system work even when I’ts cloudy.Naturally,cloud cover reduces the amount of solar radiation reaching the solar modules,but the system will generate some power on all but the most overcast days.

Solar installer should analize the site and let the consumer know the total of sun hours in your state or location,and how many sun hours in a yearly basis.Also choose if it is adecuate on the roof or a standalone pole on my yard.Places with shade are not the best options if any trees or nextdoor building create shades need to find proper place before purchasing the system,Let professional handle it.If you are a DIY I recommened to purchase a pathfinder it is the best tool for shade issues.

Sometimes people decide to do it themselves, but be awared that installing your own solar system can be a problem with inspectors,building codes,certification,permits, and your power company inspections, hire a solar professional they are qualified and certified.

When shopping for a system,get the price of every item and a separate quote for the system installation.The difference between bids may shock you.Considering the recomandation your solar system cost can be reduce dramatically for your benefit.

Help global warming and air pollution,Solar energy reduces the amount of fossil fuels that is burned also reduces CO2 that get into atmosphere,It adds value to your home and gain energy independence .Perhaps most importantly,is a great investment in a sustainable future for yourself and love ones.

Accumulation Of Sun Power In Your Home

How can the Sun power your home?

Photovoltaic (PV) cells are an arrangement of semiconductors on silicon. When sun light strikes the cell, a portion of it is absorbed into the semiconductor material. The absorbed light is transferred to the semiconductor which knocks electrons loose, allowing them to flow freely. These free electrons are forced by an electric field to flow in one direction. Once this flow of electrons is created, the current can be drawn off and collected to use in your home.

How a solar panel works.

Unfortunately, electricity is not only necessary when the sun is shining, but also when it is not so we need energy storage, or batteries. Batteries are costly and add regular maintenance to the PV system, but they are a necessity if you want to be completely independent. One way to avoid batteries is to connect your array to the utility grid, buying power when you need it and selling back to the power company when you produce more than you need. In this scenario the utility acts as an infinite storage system. The utility must allow you to interconnect your system to their power grid. This is accomplished by changing your current metering system to a net metering system. When the sun is shining brightly your meter will spin backward while you are producing peak power from your solar array. Your meter will work normally at night when your solar array is not producing energy and you are drawing power.

In a grid-tied PV system, power is generated with solar panels flush-mounted on the roof, ground-mounted in a field, or mounted on the top of a pole. The solar modules produce Direct Current (DC) while our homes and the utility grid transfer Alternating Current (AC). DC power created by the solar modules must be transferred through an inverter and converted into AC power to match the grid's power.

Grid-tied solar power

Puerto Rico power companies have a large demand for renewable electricity into their power grid making a grid-tied solar electric array the most common and financially sound way to go solar. Call or email 787-344-1643,joe.cresoto@msn.com

Solar Power Basic

Many question are ask, Is it a great idea to go solar or if it's not?What are the advantages?Its solar really good for my business or home.The advantages in going solar are the electricity supplied by a pv system displaces electricity from some other power-generating technology.If the alternative is very expensive,such as a utility connection to a remote location,then the pv system can save you alot of money.

Yes,its great having a solar system install in you're home or business,the benefits are huge but we need to consider a few things.Before we go out and purchase a system we need to know,It's they're sufficient sun hours where i live?and how many sun hours in a daily basis.We need to determine what are our needs,concerns,expectation.Hiring a professional pv installer is really the best choice, he or she can explain the process of determining potetial array location ,methods and diagramming shadding patterns.

What to really consider before purchasing a solar power system:

Need to discuss with the professional you hire,considerations in determining the suitability and condition of existing roof,stuctural systems.

Electrical systems and equipment.

Ask the professional installer to explain the function of an energy audit and idetify opportunities for conservation and energy efficiency.

What you should consider when a proposal is offer such as,estimate for cost,size of system,performance,and value of system.

Identifying these factors begins the site surveying process,which influences all other subsequent system design and installation procedures,including solar equipment,preparing bids,planning and completing pv system.Installer and designers of pv system must identify the customers need,concerns and answer all question a customer should ask.Some customers may be very informed while others may need the installerto explain the types of systems and their costs,functions,and performance.Many solar contractors provide literature to help customers identify their options.

The cost and funding is the major concern to customers.Fortunately,there are many resources for renewable energy,including financing,state and federal incentives,and credits.When discussing your needs with pv installers and have the solar system that cover your needs,ask them for information on applicable funding programs.Later,when the system is figured out,the contractor or installer can use this information to help you apply for these programs.

Also have in mind tha installers must coordinate a schedule and minimize potential delays to ensure the work is completed in a timely manner.The pv installer should discuss the installation process with the customer.Schedule should have flexibility to accommodate unavoidable delays such as weather or shipping delays.
