00:01 Beginning of recorded material, Introduction to Radio Live Green Smart:

Emmanuel:

[Righto] so I’m just going to give a short introduction and then I’ll come back to you.

Jonathan: Ok

Emmanuel: Welcome to Radio Live Green Smart and to our interview this evening with Jonathan Harf, of Jex Energy. I’m the presenter Emmanuel, and a little bit of background on Radio Live Green Smart: it’s a forum to discuss green living and eco-friendly living and importantly a forum to discuss where you see any disrespect for the environment first hand. Bring such disrespect to us, we’ll assist to expose that environmental disrespect, use the contact us form to send the details of the disrespect, please provide comprehensive information.

00:54 Introduction to alternative energy sources.

Tonight’s talk is about alternative energy sources, most of the worlds current [electric] electricity supply is produced from fossil fuels such as coal, oil and natural gas. These traditional energy sources have various challenges including but not [limit] limited to rising prices, growing environmental concerns over the climate changes and limited supply of fossil fuels. As a result, governments, businesses and consumers are increasingly supporting the development of alternative energy sources. [Renewed] renewable energy sources such as solar, biomass, geo thermal, hydroelectric and wind power generation have emerged as potential alternatives which address some of these concerns. Top

01:57 What is solar energy?

What is solar energy? Solar energy refers to energy from the sun. The sun has produced energy for billions of years [it is most] it is the most important source of energy for life forms. Solar energy technologies use the suns energy to light our homes, produce hot water, heat homes as shown in solar tankless water heater reviews and electricity. Top

02:33 Start of interview with Jonathan Harf.

Emmanuel: Jonathan is joining us

Jonathan: Yes

Emmanuel: and he’ll be talking about Jex Energy and how they look at renewable solutions. Jonathan my first question is tell us about yourself and Jex Energy and what do you do? Top

Jonathan: Ok sure, well what we do exactly is pretty much what you were going on about there, is we supply and [insall] install renewable solutions, renewable energy solutions predominantly for residential and commercial, [um] as the need is arising we moving more into the industrial sector too. What our aim [is] is to really reduce the carbon footprint and have people less reliant on the normal utilities, fossil fuels what not.

Emmanuel: Ok, [what um]what would be interesting [um] especially from our point of view as well: why should people switch to solar power?

Jonathan: Well it’s a very good question [um] very simple answer. The people are using up the fossil fuels at a dramatic rate and it is really destroying our planet. That would-be option [well] reason number 1 to kind of go green. [um] reason 2 [inaudible] the growth of the solar market worldwide has seen a huge reduction in the price of solar panels, solar grid tie inverters, it is really becoming a cost-effective way to move over. You must remember that in South Africa [um] our electricity price is still relatively low compared to a lot of the rest of the world, so the quicker people here can move over to solar energy the better for them from a cost saving point.

Emmanuel: Yeah, just before we move on, I’m curious, are you finding traction? Are you finding a little bit of resistance? Is the market buying into this still in a small way or in a big way? How do you find the market?

Jonathan: I’ll tell you something, we’ve been doing this now for 6 years, for the first 4 years there was a lot of resistance[um] people were very hesitant, the prices were high, which did cause this obviously.

Emmanuel: OK

Jonathan: In the last 2 years, this industry has literally boomed, [it’s um] we are just getting requests from every sector in the market which is brilliant.

Emmanuel: Ok, even domestic dwellings?

Jonathan: Even domestic, and that now has also come down to the fact of the drop in the prices of batteries as well as the technology increasing [um] Tesler have released their Powerwall 2 which we are installers and suppliers of,  and that battery is really changing the way people can live.

Emmanuel: Ok, is that the life of the battery or is that the cost or both? [inaudible]

Jonathan: It’s the life and the cost. They’ve been able to increase the life and reduce the cost.

Emmanuel: Ok I understand [righto]. [uh] Jonathan and then what are the different solar power solutions available either in the market or from your company?

Jonathan: Sure, so and in the market at the moment you would look at 3 different options. Top

6:10 cuts out

Emmanuel: Hello are you there? Hello?

Jonathan: There’s obviously [inaudible] hello can you hear me?

Emmanuel: You were out a little bit, just give [inaudible] please Jonathan.

Jonathan: Ok

Emmanuel: Jonathan sorry, suddenly something has gone wonky, [um] you come and go. Shall we just try again?

Jonathan: Can you hear me now?

Emmanuel: Yes, I hear you well. Top

06:36 Three options for solar power.

Jonathan: Ok, alright, so your first option would be a grid tied system, this is have solar panels and a grid tied inverter, there’s no backup or battery storage with this system [uh] typically this is a cost saving system. The only drawback obviously is that you don’t get any benefit at night time. We find this system typically used in commercial situations where they are using most of their power during the day; that being said there is space for it in the domestic area.

The next system would be what you would call your hybrid system, this would be a system typically where you would have a battery bank as well as solar panels and an inverter. The solar panels would feed the house or the offices during the day, the inverter then would change some of that solar power into storable energy into your batteries. This would be then either used on a daily or nightly basis, just a small amount not to drain the batteries or used as a backup, say for example there’s load shedding or a power outage.

And the last system is a complete off-grid system this is where you do not have any grid, any Eskom grid or any power grid and we design a system around that. We’ve done quite a lot of systems for game parks and those sorts of situations where it’s too expensive for [inaudible] Eskom line [inaudible] completely off solar energy and batteries.

Emmanuel: OK and that must be the expensive one?

Jonathan: [ah] yes that is quite pricey, although as I said as technology increases, these systems are really becoming a reality. [um] Elon Musk with Tesler, they’ve set up an entire island, one of the islands of Hawaii, that are running completely off  grid.

Emmanuel: OK, so it’s not impossible?

Jonathan: No, not at all.

Emmanuel: OK, [righto] thank you for those insights.

Jonathan: Sure.

Emmanuel: Then if we can take it a step further and maybe you can cover the domestic [uh] dwellings as well [uh] as well as the industry but also let’s look at the [indus, uh] the domestic user. What are the benefits of the solar power? Top

08:43 Benefits of solar power to the domestic user.

Jonathan: Well firstly obviously, it’s the cost saving, so [um] although the pay back is still relatively long, [um] if you factor in Eskom increases, as you know are quite ridiculous sometimes there is definitely a cost saving. Another big thing is that you no so reliant on one sort of power source, the utility, whoever it is.

Emmanuel: Yeah

Jonathan: So, it really lets you be a bit more free if you will [uh] obviously we also a green company so we believe in reducing your carbon footprint and all those sort of things.

Emmanuel: [inaudible] yeah OK. Just on the [the] grid tied that you mentioned a moment ago.

Jonathan: Yes

Emmanuel: What happens if the system produces more electricity than the house or the office dwelling actually uses.

Jonathan: Very [very] good question. So, at the moment is South Africa there’s only 1 or about 3 or 4 municipalities that allow for feedback into the grid and you get [you get] a credit in your account. There is a push now, Tshwane municipality have sort of passed it through legislation, so it will just take a bit of time and they are also going to allow for it. It [it] is a reality that it has to happen especially as our grid is under so much strain this would allow for energy to becoming back to them, even if we not getting paid the full amount you’ll still get a credit. All over the world they allow for feedback into the grid, however in places where it’s not allowed yet we do put something on called a grid tie limiter which just prevents that feedback for now but in the near future hopefully all the municipalities will follow suit.

Emmanuel: Ok so there is uptake? I take it when you started your business [inaudible] that there were no municipalities buying back?

Jonathan: None

Emmanuel: Now there are. OK

Jonathan: Yes

Emmanuel: OK so there is a growth but slow. [uh] are you there Jonathan?

Jonathan: I’m here yes [yes].

Emmanuel: The other question is, what are your most popular solutions?

Jonathan: Our most popular solutions right now I would say in the domestic market would be our hybrid solution, as I mentioned it has solar panels as well as a battery bank so you are getting the best of both worlds [um] we set up these systems in such a way that we try get people say 80-90% off grid with them.

Emmanuel: OK

Jonathan: So, it can be quiet a big saving to a lot of people. On the commercial side its definitely our grid tied system where companies are now looking at a 3-year payback on their system.

Emmanuel: As quick as that? Wow.

Jonathan: As quick as that yes. Top

11:43 Wrap Up

Emmanuel: [inaudible] OK righty [um] Is there maybe anything else you want to cover? I’m drawing towards the end of…
