FAQ


Answers:

    
1.  The PV Energy system is made up of Photovoltaic cells, DC-AC Inverter, and related electrical cables. Photovoltaic devices use semiconducting materials to convert sunlight directly into Direct Current (DC) electricity. The addition of a Direct Current (DC) to Alternating Current (AC) Inverter that is Utility grade compatible is added to the system and then connected to the building's main electrical panel.

  
2.  A system may be right for you if you meet one of these options;
  • the average electricity bills are $150 per month or more
  • The largest part of your roof faces a southerly direction. Or, there is available land on the property for a pole mounted system.
 
3.  The State of Maryland and the Federal government have changed and increased their tax credits or requirements for 2009. We have included the links to the Maryland and Federal websites for more information.

  
4.  There are four main factors that will impact how much energy a solar PV system will generate.
  • Shading - Is the largest part of the roof shaded during the hours of 9 am - 3 pm anytime during the year? Do you have enough land for placing the system at ground level on a pole?
  • Orientation - Is the largest part of the roof facing a southerly direction? A southern view of the sky increases the site's ability to convert available light into energy.
  • Angle - What is the roof angle on the property? Not a critical question and can be easily addressed unlike shading problems.
  • Array Size - The usable and available area on the roof dictates the size of the array. Find out how much area is on the roof that is not blocked by pipes or vents.

1.  Wind turbines convert the kinetic energy in wind into mechanical power that runs a generator to produce clean electricity. Today’s turbines are versatile modular sources of electricity. Their blades are aerodynamically designed to capture the maximum energy from the wind. The wind turns the blades, which spin a shaft connected to a generator that makes electricity. The Department of Energy has a great simulation of a wind turbine at work.

  
2.  A small wind energy system can provide you with a practical and economical source of electricity if:

•  the property has a good wind resource (minimum of class 3 wind). See a map for your particular area in Maryland, or NREL's National Map Resource.
•  the home or business is located on at least half to one acre of land
•  the local zoning codes or covenants allow wind turbines
•  the average electricity bills are $150 per month or more
• or, if the property is in a remote location without easy access to utility lines 

 
3.  The State of Maryland is leading the way in renewable energy. As a result, the state is providing incentives and grants to make it easier for consumers to begin adopting the technology, and create green jobs. The following links explain both Maryland's State Grant and Federal tax incentives.

  
4.  Energy Independence begins when the consumer decides to take charge of their own future. We, at H2*Sunlight, would like to help you. For wind turbines, it all begins with the preliminary step of site assessment.

  • Based on your own observations, how would you describe the amount of wind at your property? Use the Griggs-Puttnam Index as a guide. You must have class 3 or greater for the turbine to generate enough power. Also use Maryland Wind Calculator for your area.
  • Is there enough clear space to place a wind turbine in your property (for example, tall trees, and other buildings?
  • Please note that turbulence causes fatigue damage and shortens a wind turbines generator’s working life. When installing the turbine, keep away from local obstructions such as large trees and houses, or use a taller tower to ensure that the generator is well above the obstructions. Attaching the wind turbine to the building structure tends to pass the vibrations to the structure and can lead to structural problems in the future.
