Putting in Solar Panels : Is It Worth the particular Cost?

Putting in Solar Panels : Is It Worth the particular Cost?

We set up a 3. 0Kw solar array within June 2011. Each of our power bills every single quarter were in between $750 to $900 and rising. We all are a household of 4 and operate a home office, pool pump and from time to time air-conditioning in winter regarding heating and in summer time for cooling. Typically the house had very low voltage downlights during. We live throughout a sub-tropical location, so appliances with regard to winter heating and even summer cooling are usually needed just a few days per year. Our constantly rising power bills were becoming a true concern.

The Foreign federal government provides rebates for unit installation of PV (photo-voltaic) cells or solar panels for producing electricity. In each of our case, the rebate was worth regarding $4000.

In suburban areas, the sun panels feed electrical energy back into the key grid using the inverter which is connected to your electricity meter.

The particular electricity meter is definitely changed to the “smart meter” which is also mounted as part of the inverter. The particular “smart meter” actions the amount of electricity you use (bring in) as well as the amount of electricity your current solar panels happen to be putting out. smm panel bgmi uc As a person use electricity in the course of the day, the particular meter will take away your electricity use in the amount associated with electricity your energy are making.

In the event you generate more electrical energy than you will be using, your excess electricity is sold back to the electrical energy supplier for in relation to double the quantity that you acquire it for. This method applies in Queensland, where you happen to be paid around the gefällig amount of electric power produced.

It will be through selling the excess electricity back again to the distributor that real cost savings in your electric power bill can get made.
We use about 1 in order to 1. 5kW associated with power each hour or so during the time. So installing a 1. 5kW solar power system would only about cover our immediate power needs.

Given that the most savings will be from selling power back to the grid, we had to install a much larger system. Our roof size meant of which we could only accommodate a a single. 5kw system in each roof encounter. We opted to install an overall of 3kW over 2 roof areas using a special inverter that could take energy from 2 different solar arrays.

Some considerations for discovering the solar power panels:

Direction: Roof should face north or near to north to post the maximum sunshine. Within our case every single roof faced north-east and north-west and seems to work well.

Roofing slope: The panels, in Queensland, ultimately needs to be at concerning 15 degrees coming from the horizontal to pick up winter sun and not get too hot during the summer sun.

Overshadowing: Make sure the panels will not really be overshadowed during their peak creating times from trees and shrubs, other buildings, TELEVISION aerials etc. In case a panel is overshadowed, even a smaller amount, that -panel will not produce any electricity.

Peak Generating Times: typically between 10: 00am to about a few: 00pm is the average peak generating coming back the systems. The days will increase in summer through about 8: 00am to about 4: 00pm depending on roof top orientation.
Apart from incorporating the solar panels, we also undertook a few changes within the house:

The pool pump was wired for an off -peak tariff saving 50%

Typically the washer, dryer plus dishwasher were furthermore added to the particular off-peak tariff conserving 50%

The off-peak tariff cuts electrical power to these appliances between 6: 00pm to 9: 00pm every day

We eliminated all of our low-voltage lamps and replaced together with energy efficient fluoro downlights. The low-volt lights each received about 50watts each hour. The new lighting draw about 15watts, saving 70% on each light.
How much did this cost?

We spent $17, 500 for all the electrical work which include installation of typically the solar energy panels, new feets, new wiring with regard to dishwasher, washing equipment, dryer and pool pump. Given the government rebate of $4000 the total investment arrived at $13, five hundred.

Simply how much will we all save?

We simply received our first solar-boosted electricity consideration for the spring quarter. Our invoice for this moment last year was $750, and that we used 51. 7kWh of electricity.

The latest bill is $360 for the comparable period and many of us used 28. 8kWh of electricity, a new 55% saving.

Our own greenhouse gas exhausts went from five tonnes to only two. 6 tonnes, some sort of 48% saving.

When will I obtain my money back again?

We will save from least $1600 the year off the electricity bills using the addition of solar energy panels and re-jigging in our appliances. The majority of people attempt to operate out how extended it may need to find their money back (8. 5 12 months in our case).

However I believe this is the wrong question; some sort of better question is definitely: How much come back will I acquire on my funds? I have spent $13, 700 and have a return involving no less than $1600 each year. This means my investment is coming back again me 11. seven percent in savings off of my electricity bill. This is regarding double my mortgage loan interest rate, therefore I am still making money.

Just how long did it almost all take?

We utilized a nearby electrician trained in solar installations, who provided all of us with all the recommendations for reducing power, revised tariffs for our appliances and supply and set up of the solar power system. We to start with had to affect electricity supplier to ensure they would accept us supplying energy to them (2 weeks). The set up, re-wiring for tariff change-over to appliances, solar installation had taken 2 days. Typically the smart meter has been installed 2 months later.

On the side note, each of our first electricity invoice came with no mention of photo voltaic and an quantity owing of $950. A quick phone to our service provider we realised that will they had no idea we got installed the sun panels. Their construction had not up to date our details. They will reworked the expenses to it’s present $360 (a costly off the original bill of 62% or perhaps $590).

Our experience?

I don’t recognize why I anxiously waited so long to install the panels, plus would advise anyone to make this because part of their very own long-term investment.
