Panel Sizes

[Mickey]

Hi Ivan,

I can't find, on teh Nav web site, the overal dimension of the PV panels?

Also does Navitron intend to sell larger ones. IE 100W & 125W ?

Please advise?  - many thanks

Hi Mickey,

The panel size varies sometimes depending on the efficiency of the cells used. Typically, the 5W panel is around 20x15cm. The 20W is 54x42cm and the 60W 80x54cm.

We have a small number of 110W panels arriving with the next shipment, but we already have quite a few orders for these, so there will not be in stock for long.

Thanks Ivan,

I'm interested but first could you advise the size & price of the 110w?

All the best  Mickey

Hi Ivan,
I also tried to buy 2 x 60w panels last week, & was told that you are out of stock etc.
I've sent a couple of e-mails asking about delivery time, & also price & physical size of the 110w.
Are you in a position yet to bring us up to date please ?

thanks a lot mate

The new Navitron price list is on the Web site and indicates a price of £402 each for the 110 Watt version.  I called Ivan as I needed to know the size before ordering.   He said that he expected the panels to arrive in 10 days or so and only then could he go firm on the overall dims.

Hi Ivan,

You still getting 55w panels as well please ?
Apparently, the price 'per watt' was to be the same as 60's, but I note that the 110w prices have an increased 'per watt' costs.
Can you also clarify delivery dates please ? Your sales say Mid July,,,, but someone told Mickey "within 10 days".

My panel/s can't go on the roof (rented abode) so are going on the patio.  Am I supposed to use 'specific' cable to run to the property ?

Am anxious to get started now.
all the best

Ivan was not being precise - sales mid July is around the 15th and my "within 10 days"  puts us around the 15th

Of course Mickey,,,,I'm so sorry,,,,, i'm still on planet June !!!!
Many apologies Ivan.
When you have the time tho', can you comment on the other queries please ?

The reason we do not specify the sizes is that it changes from batch to batch according to silicon efficiency, which varies somewhat. Currently we have 5W, 20W, 55W and 110W in stock. The 110W are more expensive per watt than the other sizes.

My 110w panels have just arrived and the dims are:-

147 x  68 cms

Tech Spec:   Voc = 22.0V,  Vmax = 17.50V.

Can you quote a Isc as well?

[Mickey]

Isc = 7 amps
Peak = 6.3amps
Peak Power = 110w

Price per watt increases when you go over 60W - this is for a few reasons: the main one is that the germans are looking to fit as big a panel as possible as it saves on installation time (they are now producing 240w panels due to german demand) - as the germans are driving the market at the moment with excessive demand, anything less favourable to them is at better prices.

The other thing is that the 110W panels are pre-wired with easi-connect waterproof high voltage connectors for ease of installation (they look identical to SMA connectors, funny enough, which makes it potentially a solder-less installation.

Yes, the 55W panels arrived mid July as planned, although we are still trying to catch up with various things (think this situation is going to extend to beginning of September when we should be getting more staff, more stock etc).

Any cable will do as long as it can handle the carrying capacity, but check out the losses before going for small cable. Unless your cable runs are short, you could be wasting a lot of the power you are producing. Check out my wire loss calculator which is in the download area of our website.
