<p style="margin:0;padding:0;">i realize this is not popular now in these days of "solar is so cheap", but i will not work for people who wont conserve or be efficient.</p>

<p style="margin:0;padding:0;">as we all know, pv contains lots of embedded energy and to my thinking... having it power waste is simply greenwashing... so <span style="font-family: Arial, Helvetica, Verdana, sans-serif;">the "race to the bottom" will have to happen without my help.</span></p>

<p style="margin:0;padding:0;">i start every job (on or off grid) with an energy audit. the result is radically lower consumption levels, more conscious customers, a smaller system (so less resource use and less economic investment). this yields a win-win for the customer and planet. with propane/wood powering the water and space heating loads (and sometimes refrigeration), line drying laundry... generally the maximum consumption i see is in the 5 to 6 kWh/day area.</p>
<p style="margin:0;padding:0;"> </p>
<p style="margin:0;padding:0;">around here, with our seasonal precipitation it is nearly impossible to do off grid without generator use in the winter. here again, conservation helps as it reduces the overall load, battery cycling (and wear) and generator use.</p>
<p style="margin:0;padding:0;"> </p>
<p style="margin:0;padding:0;">i realize you were asking about battery cycling, but with lower consumption profiles, this becomes less of an issue.</p>
