Sri Lanka have asked the International Cricket Council to bring forward the start of day-night games when there is a chance of dew affecting the outcome.
Jayawardene believes his side are still on an upward curve
Matches have begun at 2.30pm during the current Champions Trophy in India but Sri Lanka team manager Michael Tissera says 12.30 would have been preferable.
Skipper Mahela Jayawardene, however, has offered no excuses for their first round exit from the competition.
"It was our fault that we lost and we have to accept that," he said.
"As individuals within a team, we have to put our hands up and take responsibility for our own actions."
Sri Lanka were eliminated following a 78-run defeat by South Africa, a result which Jayawardene described as "a huge disappointment".
He continued: "I can understand the frustration of the supporters. Like the fans, we also had high expectations after our successes during the past few months."
Jayawardene defended team selection decisions taken during the competition, including the exclusion of leg-spinner Malinga Bandara.
"We toyed with playing him against New Zealand in Mumbai which had less of a dew problem, but [against South Africa] in Ahmedabad it was too risky to go into the match with only three fast bowlers in case we lost the toss.
"We had to make difficult decisions based on the resources at our disposal and the likely conditions at each venue. I have no regrets about the decisions we made," he said.
Sri Lanka's next assignment is a tour to New Zealand where, apart from playing two Test matches, they will seek to rediscover their best one-day form ahead of the World Cup in the West Indies.
Jayawardene is upbeat about their prospects.
"The team has been improving fast in the past 12 months and I'm confident this will continue despite the setback in the Champions Trophy," he added.
