6 Solar Myths

 

True or False? width=

If you’re interested in installing solar, but have some doubts or questions about popular solar myths, have a read below.
We’ve answered six popular solar myths just for you.

After  a solar panel is depleted, it is actually bad for the environment.
The average lifecycle of a solar panel is 25 years.  Panels are created with recycling in mind and some manufactures will recycle them for you, free of charge.

All of the current eco-friendly, solar schemes only help the rich buy solar, which is actually subsidised by the poor.
The middle to lower income areas and suburbs with large retired populations are currently the most concerned about the environment and their increasing electric bills.  This translates to these areas also being the areas with higher instances of solar systems being installed.


Solar panels only work on sunny days.
Solar panels work on cloudy, overcast, snowy and sunny days. What will definitely impede the amount of power produced is if there is significant shading over your array of panels.  The amazing technology of solar panels, converts the light from the sun via the silicon in each of the many cells that make up a solar panel. These panels may work best on sunny days, but the maximum output is derived when the sunny days are cooler, not hotter.

This is supported by the fact that counties like China, Germany, Italy and the UK all have thriving and efficient solar take up.

 

Solar panels on my roof will make it hard for me to sell my house
According to a study by a group of economists, on average, home owners “who install photovoltaic solar panels to power their homes can recover nearly all the investment costs if they move–and that’s on top of the annual energy savings”.

They found that the payback increased even more, if the home is located in a more liberal, eco-minded community. Another study found that homes with solar panels “actually sell faster than homes without solar panels”.  Additionally, there are built insavings for the new homeowner from the future output of the panels along with any eligible feed-in tariffs.

 

Solar power systems are expensive
5-10 years ago, that was probably true, however, with the growing popularity of solar power, the combination of economies of scale (i.e. more people buying solar means costs to manufacture systems have gotten cheaper over time) and ever-improving technology, significantly prices in the last decade have significantly reduced. Average system prices are lower now than they’ve ever been before.

For example, back in 2010, a 4kW system cost somewhere around $15,000. The average price now is approx. $5,000 to$ 8,000 (with some firms selling systems even cheaper than that.) That’s a 47 to 66% drop in system prices in just five years and that price drop will continue to reduce as time goes by.

Solar panels are hard to maintain
Because solar panels have no moving parts, there is very little maintenance involved. A couple of times a year they should be looked at to clear away any dirt or debris that may have collected or built up on them.  Simple and easy instructions can be found here.

Understanding Batteries

Off-Grid Systems

For some households a battery system can be of great benefit and minimise a home’s reliance on the grid. However, it’s important to understand for a battery to be useful your solar system needs to be generating excess energy for the battery to store, which you can then use at night or when the sun is not out.

When selecting a battery, you’ll want to invest in a system that is most suited to your home and can drive the best return on investment (ROI). Despite a larger upfront cost, a higher quality battery may significantly increase your ROI.

    Battery systems start from $6,000 and costs can vary greatly based on the following factors:

  1. Cycle Life-Time

    The number of times a battery can fully charge and discharge.

  2. Battery Power (kW)

    How fast it can be charged or discharged.

  3. Storage Capacity (kWh)

    The maximum amount of energy a battery system can store.

  4. Battery Management System (BMS)

    An electronic ‘smart’ system that gathers data and manages the battery ensuring it does not overload or operate outside of its safe functioning zone..

  5. Inverter

    Battery systems require their own inverter if your solar system does not have a hybrid inverter.

  6. 'All-In-One Unit’

    A system which includes the battery, BMS and an inverter all in one unit.

  7. Warranty

    Length of time or cycles the battery system is under guarantee.

  8. Blackout Protection/Backup

    It’s important to note this is not a common feature of a battery system and could cost thousands of dollars to include. Blackout protection not only requires additional components but also a specialised installation and rewiring. For grid-connected homes, the cost for blackout protection can outweigh the benefit.

Additionally, if your purpose for adding battery is to go Off-Grid and become completely independent from the grid you will need to ensure your solar system can generate enough energy to power your home and your battery system is large enough to store this energy. For homes in metro areas going Off-grid is not cost effective and is only recommended for those in remote areas with limited access to the grid. Off-grid solar systems with battery start at approximately $30,000.
