CLEAN SOLAR ENERGY

PV PANELS

Title

Solar Photovoltaic (PV) panels produce electricity when exposed to the sun. It’s basically as simple as that, no burning of fossil fuels required and no pollution. The cost is around 2.3 euros per installed watt which makes it amongst the cheapest form of energy production especially in sunny countries. So called ‘Cheap’ petrol generators over their short lifetime consume large amounts of costly and polluting fossil fuel and are also noisy and smelly so by the end are not so cheap.

The other great feature of solar PV is combined with charging electric cars (EVs) makes for a really efficient system because solar is most plentiful in the midday sun and so as to take maximum advantage, can be stored in the car batteries for immediate or use later when there is less sun, but don’t worry you don’t have to be stationary during high solar production, there’s normally enough stored car battery power for a number of small trips and when you get used to top up charging its really simple and fun.

SIZE

Title

Solar systems are modular so you can purchase a system tailor made to your requirements and can even add to the system later as your situation allows. Correctly sizing your solar system is very important to maximise the value of your investment. To correctly size a solar system the total daily loads measured in kwh should be estimated. Looking at the invoice from your current energy provider should give you a good idea. A small apartment may consume from 5kw/hours a day if heating is sourced from gas for example whereas bigger houses, offices, shops, restaurants and factories my consume hundreds of kw/hours. Added to the calculation of loads will be your estimate of how many km you may drive a day. If your daily drive is 130km for example, that’s a complete whole charge for a 24kw/hour car battery and will have to be supplied by around 24 panels with a maximum peak power output of 6.7 kw and may cost around 15, 450 euros. For a city car the daily drive may one quarter of the above so simply divide all the numbers by 4.

INVERTERS

Title

Solar PV panels themselves do the hard part of converting the suns rays into electricity however that’s only part of the story. To be useable the DC (direct current) electricity generated from the solar PV panels has to be inverted to become AC (Alternating current) for use in domestic situations including car charging. The devices which convert DC electric current into AC current are called inverters and are a sophisticated computerised digital device that will have certain smart functions to ensure networks are supplied electricity in the correct voltage, current and frequency. Inverters can also log data and communicate so that we can track how much energy is being consumed at any given time. When we quote total solar PV installation of 2.3 euros per watt we include the cost of inverters too which may be similar in cost to the panels themselves. There is DC car charging but is mainly used for expensive fast chargers which do not form part of the initial phase of the Solar Electric Club.

NET METERING

Title

As hard as we try, it will never be the case that our mobility needs exactly match that of the electricity generated from our solar PV panels. We can add a some battery storage to help match supply and demand but there is a significant cost. Much less costly and easy to implement is to switch to the grid electrical supply when you need more than your solar PV panels are producing and conversely sell to the grid when your solar PV panels are producing more than you require. The trading of energy in this way is called net metering and is well established in the market. Net metering does require a suitable enabled inverter and certain other approvals from your electricity provider but does make sense although don’t overused this function because the 80% of the grid is powered by mainly polluting fossil fuels. Also the price of electricity you purchase from the grid is much higher the price you are allowed to sell to the grid because there are a number of taxes bundled into the purchase price that you do not get back.

BUNDLES

Title

Combining the 3 main elements of electric vehicle, charger and solar system within a one stop shop bundle that is specifically sized to suit the individual’s needs is an offer we believe adds value. We envisage in the future working with partners to offer affordable financing to facilitate such an offer. Once things start to role and we have sufficient numbers of customers then we can offer great prices courtesy of bulk purchasing.

LOCATION

Title

Roof top mounted solar PV panels are the default location, its normally unshaded and does not use up valuable ground space for other applications. Within apartment buildings regulations may require all tenants to agree to install solar panels which may be hard to obtain but try!

Other locations include exposed walls and car shade structures which has a double function of keeping your car cool and protected plus generating electricity. We have a number of special made to order cool designs you may wish to choose from or customise to your own requirements.
