    You can already buy kits like this. Plug and play, with simple connectors and include some lights. However, they are mainly designed for basic rural electrification - the ones I have seen are perhaps 100W max, with more like 30W or 50W common. The 30W system support 3 LED lights, 1 radio and a phone charger. The 50W adds a small DC low power TV to the mix. None of this is good for the type of systems we have (my SMALL system is 1270W, for example, and won't run an air conditioner or run the toaster and the kettle at the same time!).

    I think it will come. But electricity kills if done wrong, and the higher power systems are much more dangerous if done poorly.

    Ikea solar panels is not plug in and play, it designed to supplement or replace the electric supply, just like CLP and HKE HK$100k solution but at half of the price

    Hi, we are looking to join the solar community, but need a contractor. Any suggestions?
    I dont want to pay someone to learn, I would rather get someone that knows what they are doing.Thanks

    We got solar panels on our roof linked up to CLP very recently, we are still waiting for final sign off from EMSD and it's been great.

    The change in the regulations so that the solar panels can cover 50% of a village house roof with a maximum clearance of 2.5m (essentially a legal waterproof canopy over 50% of your roof, rather than lying on the floor making the roof unusable as before) and the good FiT(feed in tariff rate of $5) has meant a significant increase in recent applications. So the CLP process is a bit backlogged, took I think 2 months from when our solar panels were up until CLP installed the Smartmeter etc. Apparently they are hiring more people to help but not sure when that will make a difference, so you might have some delays between installation and actually getting hooked up to the grid like us.

    The contract we have with CLP is 15 years with the $5 FiT rate, and the solar panels are also guaranteed for 15 years. Was relatively expensive to install, approx 150,000, but it should take 4 years to recover costs and then you have 11 years pure profit at the guaranteed rate. (Incidentally the highest FiT rate in the world at the moment).

    The contractor we used did a really good job of the construction, a bit useless at keeping us up to date with the timeline change, but overall fairly responsive etc by whatsapp. They did everything from start to hopefully the finish, with EMSD in the next few days so that has been super simple.

    Anyway, drop me a PM if you want the contractors details and have any questions. We are also in Lantau (I'm assuming by your name you are too).

    Hi everyone. I have been reading these posts with great interest. Can anyone advise the best type of batteries for a small off grid solar system (i.e. for my my home office with no heavy requirements like air con), and where/how to buy them in HK? Much appreciated.

    This company appears to be UK ikea's supplier for their solar panels, interesting that they have HK office as well, wonder if they sell directly to consumers or even advise their approved contractors

    I’m interested in installing solar panels for my village house.

    The initial installation charge of $150,000 is quite expensive...

    Does anyone have any figures of how much electricity they use and how much is sold back to CLP?

    Are the annual FiT earnings of $15,000 realistic?

    Are there any maintenance issues?

    How often do you need to clean the solar panels?

    Any issues with the inverter?

    Thanks

    That doesn't sound right. The CLP FIT is the highest in the world and gives a payback period of under 5 years (yours implies at least 10). Shop around for a better deal. When looking at the price, check the components. The panels should be a very small proportion of the cost these days, the inverter the most expensive piece of equipment and labour to install around 30% of the total. If any of these don't line up you have a problem.

    The amount of power you generate will depend on your roof angle / direction and shading. If you are under a tree facing north, a lot less than in the open facing south.

    You should clean them probably once a week in HK. Although I regularly forget to clean mine!

    LG is the best quality inverter on the market at the moment and inverter quality can be quite variable. Panel quality has got pretty standardised these days. Worry about inverter brand but just choose the cheapest panels.

    Hi Katherine,

    I got the $15,000 pa from the CLP webpage, so around 10 years according to CLP figures

    https://www.clp.com.hk/en/community-...tial-customers

    Out of interest,since the system was installed, how much have you made? When was the system installed? How much did you make during the last year?

    Some company offered me two plans. One at approx 14,000. The other one, no upfront costs, but they take 75% income.

    Thanks

    we don't avail of the CLP tariff, we use it as a source of power for ourselves because we get a lot of power outages.
