Why your solar system size is larger than the inverter?

Hello Solar friends, It's Channel from PurePoint Energy. We have been getting questions from clients about their solar system size and inverter size. "Why is the system size larger than the inverter?', "Is this dangerous?", "Am I wasting power?". I am here to answer all these questions!

Why oversize your system?

• The goal of designers is to ensure maximum energy harvest from each module in the system. By doing so, designers ensure the optimal use of this high-cost system component. 

• By maximizing production per module, designers achieve the optimal specific yield of the system.

• Since a larger array feeding a fixed size inverter will result in greater system annual production, the increased annual energy harvest is spread across the system’s fixed/semi-fixed costs, which include inverters, AC collection system, permitting, interconnection fees, engineering and overhead.

Are you wasting power/ Is this dangerous?

• When the available DC power from a PV array exceeds the inverter maximum power rating, the control logic in the inverter responds by moving the PV array off its maximum power point.
• Limiting power in this manner ensures that excess power is not dissipated as waste heat in the inverter.
• The inverter components are not exposed to this excess power under normal operating conditions.
• NO, it is not dangerous at all!

Solar Ownership vs. Leasing, Which one is better?

Hello Solar friends! This is Channel from PurePoint Energy. Installing solar panels on your home is an asset to your home's energy usage and home value. They save you money from your electric bill and increase the value of your home. There are two types of ways you can go solar for your home; Ownership and Leasing. Owning your solar panels means you have invested the money necessary to completely pay for the system. Leasing your solar panels means you have agreed  to finance your solar system and pay it off over time.  Owning or Leasing your solar panels can affect your homes resale value.

Ownership

• According to a study led by the U.S Department of Energy's Lawrence Berkeley Laboratory, found that home buyers are willing to pay more for homes with solar panels that are owned. 

• The study consisted of analyzing 22,000 sales of homes in eight states between 1999 and 2013 and almost 4,000 had solar panels. 

• They found that a solar power system is worth about $15,000 to home buyers or an estimate of about $4 per watt.

Leasing

• According to an article on npr.org, they say there isn't enough data to show whether the home value of a home decreases when there are leased solar panels installed.

• Bloomberg Business states, for potential buyers "a solar lease is a liability rather than an asset and may drive people away."

• A homeowner sold his solar paneled house for $140,000, when his asking price was $155,000. He had to lower the price three times, up to the point that the price of the house was lower than the price of the houses without solar to get people interested.

When going solar for your home, both options of of Ownership or Leasing have it's advantages and disadvantages. Thinking about the long term affects on your homes resale value is important when considering which option is best for you.
